Issue: Customer has an elevator call box that connects to an existing fxo port interface on their Cisco SPA8800 device with their previous carrier. We do not support the Cisco SPA8800 and instead are attempting to use the TA924e Gen3 30ch. fxo 0/0.
The call box needs a dial plan and it seems the can configuration for the fxo 0/0 port doesn't support a way to deliver the call. It specifies in the TA900 whitesheet that the fxo port is for sip recovery. Is this all that it's used for?
