Slow, unreliable, and expensive to maintain, they\u2019re a liability in a world that demands instant, uninterrupted communication. The good news? You don\u2019t have to stick with outdated phone lines any longer. This article lays out migration paths, from SIP trunks and PRI replacements to fax over IP and number porting, and shows how to replace outdated POTS lines with a reliable, modern communication solution that is easy to manage and keeps your business connected without interruptions.<br><br>Voice AI offers <a href=\"https:\/\/voice.ai\/ai-voice-agents\/\">AI voice agents<\/a> that integrate with VoIP and SIP trunks to automate routine calls, reduce load on live agents, and simplify the transition from analog lines, helping you cut costs and maintain high uptime.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Over 36 million POTS lines remain in use in the United States, leaving many mission-critical facilities dependent on aging copper, while vendor deprioritization is increasing repair times and multi-site outage risk.<\/li>\n\n\n\n<li>POTS lines now cost businesses an average of $65 to $100 per line per month, and maintenance costs have risen about 30 percent over the past five years, turning a once-cheap backstop into a recurring financial and operational burden.<\/li>\n\n\n\n<li>Approximately 60 percent of businesses have already transitioned from POTS to VoIP, and <a href=\"https:\/\/voice.ai\/hub\/ai-voice-agents\/how-voip-works-step-by-step\/\">VoIP-based solutions<\/a> can reduce communication costs by up to 50 percent compared with traditional lines, demonstrating both migration maturity and clear savings potential.<\/li>\n\n\n\n<li>More than 70 percent of businesses plan to transition from POTS by 2025, which narrows planning windows and increases the risk of rushed, incompatible vendor choices that lead to compliance and functionality failures.<\/li>\n\n\n\n<li>A disciplined four-step program that includes a full audit, staged cutovers, a 30-day burn-in period, and 90-day vendor follow-ups, plus quarterly failover drills for a rolling 25 percent of sites, materially reduces surprise outages and regulatory exposure.<\/li>\n\n\n\n<li>Procurement and testing must enforce measurable technical thresholds and realistic TCO, because the average cost of maintaining a single POTS line is now over $50 per month, and hidden factors such as battery runtimes and monitoring can drive post-cutover failures.<\/li>\n<\/ul>\n\n\n\n<p>This is where Voice AI&#8217;s <a href=\"https:\/\/voice.ai\/app\/dashboard\/home\">AI voice agents<\/a> fit in, addressing automated call routing, automated failover triggers, and audit-ready logging to shorten incident triage windows while preserving human oversight.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Replacing POTS Lines Is Now an Urgent Priority<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-26.png\" alt=\"POTS lines - POTS Line Replacement Options\" class=\"wp-image-17795\" srcset=\"https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-26.png 1024w, https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-26-300x225.png 300w, https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-26-768x576.png 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>You might want to think again. Between 2019 and 2024, U.S. business and government POTS usage <a href=\"https:\/\/www.bbc.com\/news\/articles\/c9861edyjlno\">declined by 50%<\/a>, from 20.8 million lines to 10.39 million, according to the FCC. Prices for a single analog line have skyrocketed from $70 to over $500 per month. Repairs take weeks. Compliance risks for life safety systems are growing. They\u2019re retiring copper networks fast; AT&amp;T alone plans to end all TDM services by 2029.<\/p>\n\n\n\n<p>The window to safely rely on POTS is closing. Every month you wait increases your costs, your downtime, and your risk. Modern alternatives aren\u2019t just safer, they\u2019re cheaper, faster, and packed with features your old copper lines could only dream of. It\u2019s time to move beyond the status quo and future-proof your communications before the system you depend on disappears.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Stakes: Rising Costs, Compliance Risks, and Service Degradation<\/h3>\n\n\n\n<p>Delaying a move away from POTS lines can hit your business in multiple ways:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Rising Costs<\/h4>\n\n\n\n<p>Analog lines are becoming prohibitively expensive. A single line that once cost $70 per month can now run $500 or more. Providers are increasing prices to incentivize migration, and businesses that wait face a serious budget strain.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Degrading Service<\/h4>\n\n\n\n<p>As copper networks shrink, outages are becoming more frequent. Repair times have ballooned from a day to weeks due to technician shortages. Inconsistent service can disrupt operations, harm customer experience, and reduce productivity.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Compliance Nightmares<\/h4>\n\n\n\n<p>Many POTS lines support life-safety systems, such as fire alarms. If your POTS line fails, inspections may fail, potentially resulting in fines or even evacuation notices. For facilities like hospitals, schools, and government offices, this is not a risk worth taking.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">POTS Line Phaseout &amp; Digital Migration<\/h3>\n\n\n\n<p>It\u2019s easy to assume you can delay replacing POTS lines, but the reality is that industry timelines, regulatory changes, and provider policies are moving faster than many businesses realize. Providers are phasing out sales of analog lines, moving to support-only models, and encouraging digital migration.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Copper networks are being retired at increasing rates.<\/li>\n\n\n\n<li>Providers are no longer selling new analog lines.<\/li>\n\n\n\n<li>Regulatory incentives favor digital, IP-based solutions.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Limited Functionality and Decreased Support<\/h3>\n\n\n\n<p>Beyond cost and compliance, POTS lines are technologically limited. They don\u2019t support video calls, instant messaging, or digital platform integrations, and they lack remote monitoring, forcing staff to test lines physically, a major drain for large campuses or organizations. Support is also dwindling as telecom companies prioritize digital networks, leaving businesses vulnerable to service interruptions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Who Needs POTS Line Replacements?<\/h3>\n\n\n\n<p>Some organizations feel the impact of POTS obsolescence more acutely than others:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Businesses relying on landlines for voice, fax, POS, or <a href=\"https:\/\/sponcomm.com\/info-detail\/intercom-system-101\">intercom systems<\/a><\/li>\n\n\n\n<li>Facilities with fire alarms, elevators, and emergency phones<\/li>\n\n\n\n<li>Security and monitoring systems like burglar alarms, gates, and blue light phones<\/li>\n\n\n\n<li>Industries including healthcare, education, and government<br><\/li>\n<\/ul>\n\n\n\n<p>For these users, moving away from POTS isn\u2019t optional; it\u2019s critical.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Opportunity<\/h3>\n\n\n\n<p>Modern communication solutions are feature-rich, cost-effective, and scalable, providing capabilities POTS lacks, including reliable connections, advanced functionality, and future flexibility. Migrating now ensures your business stays connected, compliant, and ready for the next wave of digital communications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Related Reading<\/h3>\n\n\n\n<ul

1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">1. Voice over Internet Protocol (VoIP)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Works for<\/strong>: Replacing bulk POTS lines across offices, enabling remote agents, and modernizing call features while keeping an on-site PBX or moving to hosted voice.<\/li>\n\n\n\n<li><strong>Not for:<\/strong> Environments that cannot guarantee basic IP connectivity or power, or single-circuit sites where regulatory hardware requires analog signaling without adapters.<\/li>\n\n\n\n<li><strong>Benefits:<\/strong> VoIP reduces long-distance and interoffice charges by routing voice over your existing data network and scales without rewiring. VoIP also enables softphones, multi-device ringing, and SIP interoperability, allowing you to preserve PBX investments while adding modern features.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Voice over Cable (VoC)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Works for: <\/strong>Sites served by cable broadband where fiber or Ethernet circuits are not cost-effective and a fast, turnkey installation is needed with minimal on-site rewiring.<\/li>\n\n\n\n<li><strong>Not for: <\/strong>Locations with highly specialized signaling needs, or mission-critical systems that demand carrier-grade SLAs beyond what regional cable operators provide.<\/li>\n\n\n\n<li><strong>Benefits:<\/strong> VoC uses the cable provider\u2019s network to prioritize voice, so installs are quick and call quality is reliable on both coax and <a href=\"https:\/\/www.gartner.com\/en\/information-technology\/glossary\/fttp-fiber-to-the-premises\">FTTP<\/a>. This option reduces project complexity because voice runs over the same handoff you already use for the internet.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. SIP Trunking<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Works for:<\/strong> Businesses that want to keep an on-premises PBX but shed TDM trunks, or call centers that need granular channel scaling and advanced failover.<\/li>\n\n\n\n<li><strong>Not for:<\/strong> Installations lacking sufficient bandwidth or QoS controls, or very small offices where a full PBX plus SIP trunk is costlier than a hosted service.<\/li>\n\n\n\n<li><strong>Benefits:<\/strong> SIP trunking lets you buy call paths a la carte, improving cost efficiency and avoiding the fixed-channel blocks of PRI. It also supports multimedia and built-in network failover, so calls can automatically route to backup numbers or mobile devices. Because SIP can emulate PRI for legacy PBX gear, migration can be staged without forklift upgrades.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Cellular and Wireless POTS<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Works for: <\/strong>Hard-to-wire locations such as elevators, remote outbuildings, temporary sites, and legacy devices that require an analog dial tone, including certain alarm panels and elevator phones.<\/li>\n\n\n\n<li><strong>Not for: <\/strong>Primary site voice for high-volume contact centers or locations that require consistent latency and QoS for large concurrent calls.<\/li>\n\n\n\n<li><strong>Benefits: <\/strong>Wireless POTS delivers analog service over LTE and 5G without copper, enabling faster installation and reducing construction costs. It provides a simple analog interface for legacy endpoints while eliminating dependence on a single copper circuit.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5. Cloud-based Phone Systems<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Works for:<\/strong> Distributed teams, hybrid workforces, and organizations that want to remove <a href=\"https:\/\/www.modn.com\/blog\/everything-you-need-to-know-about-installing-and-maintaining-pbx-systems-for-enterprises\">PBX maintenance<\/a> from internal IT responsibilities.<\/li>\n\n\n\n<li><strong>Not for:<\/strong> Sites where strict on-premises hardware is legally required, or where internet redundancy is impossible to achieve.<\/li>\n\n\n\n<li><strong>Benefits: <\/strong>Hosted PBX and UCaaS centralize voice, video, messaging, and collaboration, and providers take on patches, upgrades, and failover. Cloud services make scaling trivial, convert capital expenditures into predictable subscriptions, and simplify disaster recovery because the core telephony is not tied to a single building.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6. Microsoft Teams (Direct Routing)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Works for: <\/strong>Organizations already standardized on Microsoft 365 that want to unify external calling with internal collaboration and tracking.<\/li>\n\n\n\n<li><strong>Not for:<\/strong> Companies that require specialized telephony features not supported by Teams, or environments that cannot tolerate adding another dependency on a single collaboration platform.<\/li>\n\n\n\n<li><strong>Benefits: <\/strong>Direct routing lets you keep your telephony provider while making calls from Teams, so users get a single app for chat, meetings, and PSTN calling. That streamlines workflows and makes analytics and call recording consistent with the rest of your collaboration data.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">7. Analog Telephone Adapters (ATAs)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Works for: <\/strong>Phased migrations where you must keep analog phones, fax machines, or point-of-sale terminals functioning while moving core voice to IP.<\/li>\n\n\n\n<li><strong>Not for:<\/strong> Long-term sole reliance when you want full VoIP feature parity across the fleet, because ATAs add complexity and can be a maintenance burden at scale.<\/li>\n\n\n\n<li><strong>Benefits: <\/strong>ATAs are low-cost and low-risk adapters that bridge legacy analog devices to your VoIP network.

Legacy signaling and alarm panels expect analog timing and line characteristics; gateway latency can corrupt alarm tones; and forgotten battery backup calculations can leave elevators and emergency phones dead during power events.<\/p>\n\n\n\n<p>Technicians and facilities managers report installation rejections and sleepless nights when inspectors flag systems as noncompliant, and teams feel crushed by surprise remediation work. Simplify your POTS line replacement process by taking this four-step approach.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Audit Your Current Infrastructure<\/h3>\n\n\n\n<p>List every copper endpoint and its function, including elevator phone lines, door-entry intercoms, fire alarm panels, fax machines, PBX trunks, modems, security or boiler-room alarms, gate or pool emergency phones, and point-of-sale systems.<\/p>\n\n\n\n<p>For each circuit, capture the physical pair, signaling type (loop start, ground start, dialer tones), required test patterns, and the approving authority for compliance. Then classify each line as must-stay analog, candidate for adapter, or ready for digital migration.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Stakeholder Mapping &amp; Failure Planning<\/h4>\n\n\n\n<p>Interview users and build a stakeholder map to surface failure scenarios they cannot tolerate. Meet with the IT team to map QoS, <a href=\"https:\/\/www.techtarget.com\/searchnetworking\/definition\/virtual-LAN\">VLANs<\/a>, and power capacity. Deliverables should include a dependency matrix, a one-page acceptance criteria sheet for each device, and a timeline showing the incumbent carrier&#8217;s planned sunsets and service changes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Choose the Right POTS Replacement Solution<\/h3>\n\n\n\n<p>Match replacement technology to the dependency class you created. Evaluate network redundancy and failover by running a simple stress test, simulating the primary path failing, and verifying the candidate solution completes a full alarm transmission within your required window.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Verify Industry Compliance<\/h4>\n\n\n\n<p>For example, NFPA 72 requirements for fire signaling, by obtaining written confirmation from vendors and, when needed, a pre-approval letter from your authority having jurisdiction.<\/p>\n\n\n\n<p>Check legacy compatibility by factory-testing one representative device per vendor model in a lab rack, logging signaling traces, and confirming supervisory tones. Document total cost of ownership, including provisioning, local power, and battery runtimes, monitoring, and ongoing support, so decision-makers can see both the hard savings and the operational tradeoffs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Plan for Installation and Training<\/h3>\n\n\n\n<p>Work with a provider to co-develop a phased timeline that preserves business continuity. Define a rollback plan for every cutover step, an acceptance test script, and an escalation matrix with specific RTO and RPO targets. Train technicians using real gear; they will touch and record short video guides of the exact cutover procedures.<\/p>\n\n\n\n<p>Require the vendor to provide remote monitoring, a single point of contact for emergency escalations, and a schedule of follow-up visits during the first 90 days. Include a formal handoff package that lists firmware versions, configuration snapshots, and battery test certificates.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Test and Optimize<\/h3>\n\n\n\n<p>Run acceptance tests that cover real failure modes, such as loss of primary network, power outage with battery-only operation, partial packet loss, and busy-hour call concurrency. Validate alarm panels against the local inspector\u2019s test script, not just vendor claims. Integrate redundancy checks such as <a href=\"https:\/\/fidalia.com\/backup-internet\/the-hidden-risks-of-using-lte-failover-for-backup-internet\/\">LTE backups<\/a>, and test them under load.<\/p>\n\n\n\n<p>After cutover, treat the first 30 days as a burn-in, collecting telemetry, ticket volumes, and mean time to acknowledge. Use that data to tune QoS, revise failover timers, and update the stakeholder playbook. Keep a living lessons-log to prevent repeating mistakes across sites.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Small Analogy That Clarifies the Difference<\/h3>\n\n\n\n<p>Think of a migration like replacing an engine on a delivery truck while it is still making runs. You can swap parts in a garage, or schedule controlled downtime, stage the replacement engine on a lift, test the drivetrain, and only then send the truck back out. Doing the first leaves you stranded on the highway; doing the second costs time up front but prevents expensive, public failures.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Optimize the Right POTS Replacement For Your Industry<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-29-1024x512.png\" alt=\"Choosing the right vendor - POTS Line Replacement Options\" class=\"wp-image-17798\" srcset=\"https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-29-1024x512.png 1024w, https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-29-300x150.png 300w, https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-29-768x384.png 768w, https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-29-1536x768.png 1536w, https:\/\/voice.ai\/hub\/wp-content\/uploads\/2026\/01\/image-29.png 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Choose replacements based on risk, function, and enforceable measures, not on feature lists. For each site, score regulatory exposure, human impact of failure, and restoration cost, then select the technology that minimizes that composite risk while meeting clear acceptance metrics. Build contracts and validation tests around those metrics so vendors deliver what matters in your industry.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Should Healthcare Teams Judge FoIP and Vendor Obligations?<\/h3>\n\n\n\n<p>Treat <a href=\"https:\/\/compliancy-group.com\/what-is-hipaa-compliance\/\">HIPAA compliance<\/a> as just the baseline. Require a signed Business Associate Agreement that names specific safeguards, breach notification timelines, and audit windows, and demand SOC 2 Type II or third-party penetration test reports as proof.<\/p>\n\n\n\n<p>Define acceptance tests that matter to clinicians, for example, a fax round-trip success rate target and end-to-end delivery confirmation for PHI within a specified timeout. When we map vendor promises to surgical workflows, decisions become measurable obligations you can enforce during cutover.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Procurement Language Protects Building Owners and Property Managers?<\/h3>\n\n\n\n<p>Insist on code-acknowledgement letters from vendors stating compliance with the specific standard that governs each device, and put those letters into the contract. Add clauses requiring on-site spare-unit provisioning, quarterly remote diagnostics, and remote firmware control to avoid being stuck with unsupported hardware.<\/p>\n\n\n\n<p>Make mean time to repair and on-site response time contractual, tie service credits to missed RTOs, and require monthly status reports through a centralized management portal so you can spot degradation across a portfolio before tenants notice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Do Retailers Size and Validate Backup POS and Alarm Backups?<\/h3>\n\n\n\n<p>Calculate the true cost of a failed transaction, then multiply it by peak hourly throughput to derive a risk exposure for each location. Use that to justify a cellular path with SIM diversity, or a hybrid SIM-plus-wired failover that automatically switches within a defined window.<\/p>\n\n\n\n<p>Bench-test the failover by simulating a network outage, forcing the POS to switch, and recording the time to transaction completion; require the vendor to meet that time in acceptance testing. Remember to include roaming and data cap guarantees in the contract so a seasonal store does not get throttled during peak hours.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Operational Tests Prove Campus and Education Emergency Phones Will Perform?<\/h3>\n\n\n\n<p>Plan staged, observable drills that replicate realistic failure modes, not just lab pings. Run a blackout test with battery-only operation for the intended runtime, then trigger multiple simultaneous emergency calls to validate concurrency handling and alerting to the facilities dashboard.<\/p>\n\n\n\n<p>Capture telemetry for 30 days post-cutover, and use KPIs like time to acknowledge, successful call completion rate, and battery health variance to tune thresholds. If the facilities team cannot remotely view device status, you will have a blind spot that will lead to costly repairs later.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Should Manufacturing Teams Think About Gate and Alarm Integrations?<\/h3>\n\n\n\n<p>Prioritize deterministic behavior under power events. Require battery runtimes sized to your longest plausible outage and mandate external UPS monitoring in the vendor portal.<\/p>\n\n\n\n<p>For gate lines, specify signaling compatibility tests with the exact controller models in your yards and run live handoff tests during a maintenance window. Use a weighted prioritization score to stage rollouts, placing the highest-scoring sites on cellular backup first, as a single gate outage can cause hours of lost throughput.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Technical Thresholds and Monitoring Capabilities Should You Require?<\/h3>\n\n\n\n<p>Ask vendors for measurable targets, like a critical alarm call completion success rate goal, packet loss tolerance thresholds, and maximum failover time in seconds. Insist on remote configuration, over-the-air updates with rollback, per-device alerts for battery health and SIM status, and an API feed so your monitoring system can ingest events.<\/p>\n\n\n\n<p>Require field validation reports, including signal strength surveys with dBm readings, and set minimal acceptable signal windows so cellular solutions are not deployed where coverage will later fail.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A Practical Budgeting Note You Cannot Ignore<\/h3>\n\n\n\n<p>Budget models must reflect ongoing reality, not optimistic invoices. Factor recurring maintenance into TCO using the latest market trends; for example, maintenance costs for POTS lines have increased by 30% over the past five years. The 2025 Guide to Transitioning from POTS Lines to Modern Technology.<\/p>\n\n\n\n<p>Also run per-line maintenance scenarios against the baseline cost, since the average cost of maintaining a single POTS line is now over <a href=\"https:\/\/www.linkedin.com\/pulse\/2025-guide-transitioning-from-pots-lines-modern-technology-baez-5iple\">$50 per month<\/a>. The 2025 Guide to Transitioning from POTS Lines to Modern Technology, then compare that to provider SLAs and your projected support overhead.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Which KPIs and governance steps stop regressions after migration?<\/h3>\n\n\n\n<p>Track device-level mean time to acknowledge, alarm transmission success rate, battery health slope, and percentage of sites with SIM diversity. Require quarterly governance reviews with vendors, review lessons learned from each cutover, and run at least one forced failover drill per quarter for a rolling 25 percent of sites, so tactics are practiced before they are needed. Treat the first 90 days after a cutover as a monitored trial, with mandatory remedial actions specified in the SOW.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Modernize Voice Communication After POTS Without Losing Reliability<\/h2>\n\n\n\n<p>Most teams keep their old phone workflows after decommissioning POTS because changing call paths feels risky and disruptive.
