I have Cisco Voice router 2801 with Two FXO ports and we have terminated two PSTN lines over it. Suddently, we are facing some DTMF detection issues.
Once the Router give us the dial Tone and we tried to dialed the desired numbers but unfortunately some times router recived the wrong digits. Successful ratio is 30% means 3 calls are passing correctly out of 10.
Recived Sample 1: 92233326631116
Recived Sample 2: 9223266
Please help me to sort out this issue. Thanks.
Note: its works perfectly since couple of years.
