No ringback tone when CCM IP Phones call CME IP Phone

raymond.lai · ‎05-31-2005

THe CCM 3.3 has set up the H323 Gateway and it is pointing at the IP address of the CME. When IP Phone of CCM system calls IP Phone at CME, the IP Phone at CCM does not have ringback tones but the call can be established.

On the CME router, where can I put those progress_ind alert command as I cannot put any commands on those auto-generated dial-peer voice 2000X pots for the ephones.

Thanks,

On the CCM route pattern pointing to the h323 GW check "Provide Outside dial tone" checkbox.

Raymond,

I think you can put the command of "incoming called-number ." on the VOIP dial-peer which points to CallManager on CME router, then the CCM IP Phone can hear the ringback tone.

Hi,

the guys below are not correct. The outside dial-tone and incoming called-number have nothing to do with the ringback.

Login to your Cisco router and run "debug cch323 h225". Make a call and see if any ALERTING messages comes to the router.

CallManager has a problem where it does send ALERTING message, but with no PI (Progress Indicator) inside.

You have three choices:

1. Put the "tone ringback alert-no-pi" in the pots dialpeer.

2. Put progress_ind setup 1 and progress_ind progress 3 at the pots dial-peer.

3. Check in the CCM if the ringback is set to H225 UserInfo.
