Gateway Troubleshooting: Ringing Stops on IP Phone Calling TDM
Ringing Stops on IP Phone Calling TDM
|Problem Summary||Ringback tone is clipped when an outbound call is placed from TNP IP phones to a TDM endpoint. For IP originated calls whose destination is a TDM endpoint, and the call goes through Unified CVP, this shows up when the call originates from TNP phones (7971, 7970, 7961, 7941).
User experience will be something like that given in the call flow example below:
|Possible Cause||The appropriate settings were not made on the Gateway that is placing the outbound call.|
|Recommended Action||Apply the following setting on the POTS dial-peer on the Gateway that is placing the outbound call to the TDM destination:
GW(config-dial-peer)#progress_ind alert strip
|Associated CDETS #||None.|
