Can someone tell me how to turn on DTMF relay on a POTS dial peer or even in global config??? What is happening is when we make a outbound call and the call is connected, an IVR is on the line as the calling party. When the called party presses keypad, DTMF is not returned to the calling party.
I have a AS5350XM with c5350-jk9su2_ivs-mz.124-24.T8.bin IOS
dial-peer voice 156 pots

Thanks
