Analogue phone on FXS port unable to call out via QSIG

We have connected an analoge phone to an FXS port and if we make a call via the QSIG card on the same router the call drops out as soon as it connects, calls from IP phones on the same router work OK.

A debug give an output of CAPABILITIES MISMATCH.

The analoge phone can call IP phones OK.

Re: Analogue phone on FXS port unable to call out via QSIG

The debug error message CAPABILITIES MISMATCH indicates you have codec mismatch between the phones used , I think changing the codec used with analog phone could solve you problem . For more information about this you can check out for the following link
