The one thing I missed...Fast Start with G.729 on the CCM Trunk. Thought I tried it, but apparently not! Curious though, in lab 1 of volume 3 this scenario does not have FastStart checked on the GK Trunk. Should it work without that?

One more thing to try if you haven't already I don't know how many DSP's you have available. Bring down the max sessions down to "2" (in both places) and # of units down to "1" followed by no sccp/sccp. I've seen strange things happen when you exceed the max sessions you "really" have. -- Vik Malhi - CCIE #13890, CCSI #31584 Senior Technical Instructor - IPexpert, Inc.

I have also tried (and currently using) non-GK controlled ICT to take GK out of the mix (just incase). Calls go through fine with g711 forced end to end, but with 729 to CME they fail. Attached is the config as it stands right now. ________________________________ From: Vik Malhi [mailto:vma...@ipexpert.com] Sent: Monday, February 23, 2009 12:22 PM To: Kevin Hogan (kevhogan); OSL Group Subject: Re: [OSL | CCIE_Voice] CCM-->CUE call fail Check the output of "show sdspfarm units" on the CME- how does it look?

A problem here would also cause dead air on calls to CME phones - if the two things above are fine then remove the need for the xcoder. Change the DP on the trunk, change your incoming dial-peer codec, remove any bandwidth CAC on the GK and test g711u end to end. -- Vik Malhi - CCIE #13890, CCSI #31584 Senior Technical Instructor - IPexpert, Inc.
