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?

No luck...Here is the NM that I am using for DSP Farm (using
different NM for PRI just to make sure it wasn't a conflict or
something):

As you mentioned, I changed DSP Farms, IOS, tried ICT, GK-ICT, with
MTP on CCM, without MTP on CCM and everything else I can think of.
Also went through a bunch of TAC cases (Cisco employee) and tried
everything I could find. I am lost on this one!

I see that the DSP is engaging from a previous post and that you
have changed your DSPfarm too so that removes the possibility of HW
problems. 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.

Just erased the config, re configured it with same result. 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.

Check the output of “show sdspfarm units” on the CME- how does it
look?
Also can you send your full CME router config.

Can ping the 6608 Xcoder IP from the CUE and other way. G711 works
fine. Hmmmm.

Sounds like a routing issue somewhere along the media path.
- Check the default gw for the CUE.
- If the call is passing through an MTP on the CCM side check the
xcoder default gw (6608). 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.

Already have it in there (forgot to put that in last email) and the
call is hitting it. Still dead air when CUE answers. Here is the
incoming DP it is hitting:
dial-peer voice 1001 voip
translation-profile incoming strip-prefix ---strips tech prefix.
incoming called-number 2#3... ---tried with "." just incase, but
no luck
no vad

I think you need an inbound VOIP dial-peer in order to fix the
codec to g729 and thereby intiating the transcoder.
Try this:
Dial-p v xx voip
incoming called-number .
codec g729r8 !! DEFAULT COMMAND- FYI only

Subject: [OSL | CCIE_Voice] CCM-->CUE call fail
Have CCM---> GK Controlled ICT (G.729) -- > CME --> CFNA (or direct
to VM) -->CUE.
With IOS 12.4(3) call gets to CUE, but no audio. With IOS 12.4(23)
call gets fast busy (tried changing IOS incase DSP firmware issue
or bug).
I have xcoders on CME...here is the output of show sccp:
SCCP Admin State: UP
Gateway IP Address: 192.168.1.1
Switchover Method: IMMEDIATE, Switchback Method: GUARD_TIMER
Switchback Guard Timer: 1200 sec, IP Precedence: 5
Max Supported MTP sessions: 0
User Masked Codec list: None
Transcoding Oper State: ACTIVE - Cause Code: NONE
Active Call Manager: 10.1.202.1, Port Number: 2000

Active Call Manager: NONE
TCP Link Status: NOT_CONNECTED
Call Manager: 10.1.202.1, Port Number: 2000
Priority: 1, Version: 3.1 or Higher
The "Max Supported MTP sessions: 0" seems strange to me. Not sure
if that is normal or not. If I use g.711 throughout the call goes
through fine.
