CME, transcoder with NM-HDV

Testing the CME transcoder functionality to access CUE via CME from CCM IP phone but it doesn't work with NM-HDV even works okay with matherboard PVDM2. CME router IOS12.4(3e), CME 3.3 and CUE2.1.2

IP phone--CCM--GK--CME(CUE)

The call from CCM IP phone successfully forwared to CUE based on the debug on CUE but silent on the phone. only one session in " show sccp connection" and randomly change the codec to g729 and g711. sometimes display both codec(two session) but silent also that this moment. please advise to resolve the issue.

Re: CME, transcoder with NM-HDV

Can yoy paste your CUE dial-peer configs on the router as well as the incoming dial-peer which matches the call coming in from call-manager.

Re: CME, transcoder with NM-HDV

Here the CUE and CCM(incoming) dial-peer. the call hits the dial-peeer as I expected but looks the problem is related to sccp(?). It works okay when I test with PVDM2

Re: CME, transcoder with NM-HDV

update the testing. transfer is always okay versus the problem on the call-forwarding.

-transfer: CCM(2001) dial 4001(CME) and trasnfer to CUE by using the transfer button --> works okay.

CME#sh sccp connections

sess_id conn_id stype mode codec ripaddr rport sport

7 8 xcode sendrecv g711u 10.253.66.254 2000 21556

7 7 xcode sendrecv g729 10.253.66.254 2000 24672

-Call-forward: 2001 dial to CUE direct or call-forwarded by 4001 --> only one session with randomly change the codec type.

or

CME#sh sccp connections

1 1 xcode sendrecv g729 10.253.66.254 2000 25154

Again, this happen with NM-HDV. PVDM2 is works perfect. Advise please.

Re: CME, transcoder with NM-HDV

I have seen this issue also with version 12.4(3)f. I had to upgrade to at least 12.4(5)b for it to finally work with the NM-HDV.
