Analog telephone service
Retain a validated analog phone while the external network moves to SIP.
Move analog phones, fax machines and other validated devices onto an IP voice network through OpenVox FXS and SIP access with a controlled replacement plan.

The analog dependency
A retiring POTS connection may still support a phone, fax machine or another analog device with a specific calling behavior.
The project must identify each dependency, determine whether the device can move through FXS access and validate the SIP service before the original line is removed.
