CME not forwarding calls to CUE

[ashleyisa]

I have deployed a new CME/CUE on a new site. when a user on site calls another user, the voicemail gets triggered. If an external call comes in, the voicemail will not trigger. I thought initially it was a H323 to SIP issue, so I changed incomming to SIP, but still the VM fails to trigger. Pls see failing trace

someone else just had this and one of the cisco guys came up with the solution.

first, get a debug using "debug ccsip messages" to find out if you are using the 'moved temp' divert, if so, use the

'no supplementary service sip moved temporarily' command under the telephony interface and try again.

May not be this but its worth the first shot...

Hey Tobin, thanks for the quick reply.

I tried to add the command you advised, but it did not resolve my issue.

I ran the sip debug command again and see failure msg 501 Not Implemented.

This is what creates my disc code 65

Found this on another cisco page:

501 - This response indicates that the server or gateway does not support the functions required to complete the request.

Wondering if the fact that i'm using a 2801 may be my issue?

IOS is - c2801-ipvoice_ivs-mz.124-22.YB4.bin

whats your dial-peer to the module look like?

are you sure you have sip-notify as the relay and G711 as the codec?

Can you post the SIP debug

hiya, ok, I think you are going to need a transcoder on the box.

1. call comes in to phone 1016 -

2. call is rebuffed using sip moved-temp message

3. call is re-originated from the source to cue module listing codec G729 only

4. cue fails call due to non overlapping codec capability

You are going to have to transcode between 729 and 711, what happens if you get rid of the supp services as mentioned before, does the call use a different method? could you do a sip trace of this scenario.

Or create a xcoder on the box.

Whats the inbound dial-peer look like (700), can you change the codec to g711u for testing?

hey tobin, sorry for the late reply. i've been researching getting transcoding to work on the CME, but have not had much joy

with it. i proved the issue as you said, by changing the wan link to 711 and i hit the vm. but getting transcoding to work is an is

sue, i cant find commands to support a CME/CUE without CUCM in the topology. I found a statment in a

cisco file:

Restrictions for Conferencing and Transcoding for Voice Gateway Routers
•DSP farm services communicate with Cisco Unified Communications Manager using Skinny Client Control Protocol (SCCP); other protocols are not supported.
•DSP farm services are not supported for Cisco Survivable Remote Site Telephony (SRST) or Cisco Unified Communications Manager Express.

Surely a standalone CME can transcode??

I have resolved the issue.

The fault was transcoding, here is the config for anyone interested:
