Transition from Analog Lines — The Time Is Now!
If your business still uses copper POTS lines, it’s time to switch.
In 2019, the FCC removed requirements for providers to maintain copper line infrastructure, paving the way for new, more efficient technologies.
Why move to SIP trunks?
-
Up to 50% of analog lines will be decommissioned by the end of 2025
-
New analog orders stopped after September 2024 for most carriers
-
Costs for analog lines are skyrocketing
-
SIP trunks offer lower costs, improved call quality, and support for Kari’s Law and Ray Baum’s Act compliance
-
New, affordable analog delivery alternatives are available — ask us for details

Don’t Let Your Contract Auto-Renew

Your savings could even cover the cost of a new VoIP system!
