Re: CME, Call forward to CUE from CCM IP phone

I realized its codec issue since I setup g729 in CCM. works if I shutdown the gk and re-routing via PSTN with g711.

configured transcode in CME but another problem is get a silence(no welcome prompt) in the CCM IP phone even successfully forwared the call to CUE and display on the CCM phone "Connected". follows the CME output before and after call setup. advise please.

1) before call setup

CME# sh sdspfarm sessions summary

4 1 IDLE -1 0 G711Ulaw64k /20ms

2) after call setup

Re: CME, Call forward to CUE from CCM IP phone

It works by restart the CME router and have a question the sip-ua output. I have two media streams but the 2nd shows "STREAM_IDLE". I think this is for g729 connected to CCM via h323 gk. Can I get an explanation why?
