Hi All,


I have below CME setup and i am able to call from Analog phone connected to FXS port to all PSTN numbers but unable to receive call from PSTN on to the analog phone connected to FXS port. I can see the PSTN call is hitting my FXO port but cannot receive call on to my analog phone. Can any one help me?

On the inbound call from telco  to the FXO, does the analog phone on FXS port even ring ?

I'd suggest to change ring number to a lower value (say 2 or default) and then shut/no shut

the port so that we close the loop quicker.

Can u pl. make that change and test?

If it still fails, can u provide deb voip ccapi inout and deb vpm sig along with config?
