CME 4.1 and call forward problem - NO TALK PATH

Hi guys. I have a CME 4.1 system with a SIP trunk for outside lines to my ISP/telephony provider. Everything works great except call forwards. The system forwards the call but neither end can talk or hear one another.

I need help with this ASAP, thanks!

For the traces you sent previously, can you check the media endpoints? Probably they want media to go back to you, in which case you can try configuring a voice class with media flow-through.

Try creating a voice class with the media command, and apply on all relevant voip DPs.

Re: CME 4.1 and call forward problem - NO TALK PATH

Well this is weird. I do not have the media command available under a dial-peer, voice class, or global voice config. I only have "media statistics"

I am running IOS 12.4-15T3

Any other ideas?

Thanks for your continued help.

That might be because you do not have ip-to-ip gw image. In fact, for what you're doing, I suspect such image is required.

Keep in mind the SIP trunk I am connecting to is a Broadsoft VOIP server, not Cisco. I dont know if it matters.

That images is not available for the 1760.

Here are my options:

Platform: 1760

Release: 12.4.15T5 ( ED - Early Deployment )

Narrow your choices by choosing a major release.

12.4 12.3 12.2 12.1

Understand.

Unfortunately I think that something is wrong with the media endpoints when a call is forwarded sip-to-sip, and I'm not sure what you can do about that.

I just reviewed the CME docs and I am running the correct image to support CME. It looks like the IPtoIP gateway was stopped with IOS 12.3

Re: CME 4.1 and call forward problem - NO TALK PATH

OK I have signed up for the Broadvoice bring your own device progam to test call forwarding. Guess what same problem.

I am thinking this has to be something on the CME side now.

Any other ideas?
