CNF files updating complete

CME(config-telephony)#

Step 3: Check Sessions

CUE# show voicev ses

Mailbox         RTP User ID                         Phone MAC Address
1002            No  phone2                            0026.0BD6.FF41

CM to CUE Voicemail problem

scenario #
CM -> Gatekeeper -> CME -> CUE

Problem
When CUCM user calls CME User and reaches voicemail, the call fails. they get a fast busy tone.

I had a look to see whether it was transcoding, but it wasnt

CME#sh scc connections

Total number of active session(s) 0, and connection(s) 0
CME#

i came to the realisation that the incoming dial-peer was negotiating a codec,

!
dial-peer voice 2300 voip
translation-profile incoming in
voice-class codec 2
incoming called-number .

voice class codec 2
codec preference 1 g729r8
codec preference 2 g711ulaw

in this case it negotiated inbound to g.729.

Since CUE is g711, here it is supposed to invoke a transcoder, but it wasnt

when i removed the voice-class codec call was successful

dial-peer voice 2300 voip
no voice-class codec 2

In summary, i dont know if this is a bug or something, but once the codec has been “negotiated” the CME fails to invoke the transcoder. By removing the codec negotiation, the transcoder was invoked and call was successful

CME#sh scc conn
