Hi,
After we have converted from ISDN to SIP we are not able to make any recordings using the CCX, i have read the documentation and can understand that CCX do not support G711alaw recording. The SIP provider is sending G711alaw so i need to convert it to G711ulaw. I have tried to make a specific dial-peer in the cube to force it running G711ulaw but then i get SIP 503 service unavaible. I have assigned MTP resources to the SIP trunk pointing at the CUBE. Does any one have an idea how to find a solution on this one?

You should be able to do this. You will just need to configure this using a different identifier on your sccp config.
eg
sccp local GigabitEthernet0/0
sccp ccm 9.13.29.30 identifier 1 version 7.0 -- Use its own IP address
sccp ccm 9.13.29.40 identifier 2 version 7.0--uses cucm ip address

associate ccm 2 priority 2

keepalive timeout 10

What we did, was to create a new audio codec preference list which had G711 u-Law over a-Law. Then, create a new Region, and put the UCCX ports into that. Finally, modify the UCCX Region relationship to the other regions (e.g. the region your SIP trunk is in) and select your new audio codec list.

Thanks Gorden i will try to create a new port group and make the Codec preference list in next week.
I will let you know the result.

If your provider is only sending you g711alaw, then changing your codec preference list won't help you. To force your CUBE to use G711ulaw, you will need to have an on board xcoder on the cube to convert G711a to ulaw. You will then configure your outbound dial-peer oto cucm on cube to use G711ulaw
An onboard xcoder is different from a cucm registered xcoder..
Here is a link that has config examples

Right now we are actually using some MTP ressources in the CUBE which is registered with the CUCM, would it be possible to have registrations against the CUCM (MTP) and locally to the CME (XCODE).

It did work with local transcoding. Thanks
