SIP Trunk Transcoding help

SHANE FREESE
Level 1
Level 1

I really just need pointed to the right documentation.  I've searched and I can't find it even though I know I've done this before.

Setup:

SIP Trunk --> 2821 --> PBX

The PBX is not a call manager.  We are using the 2821 basically as a SBC.  So SIP to SIP and everything works fine.  However some calls from the SIP provider come in as 729 instead of 711.  The PBX is not licensed for 729.  So I would like to configure transcoding on the 2821 to transcode those calls.  I have DSPs installed but I cannot find the documentation on how to configure the transcoding without a call manager on the other side.

Can someone point me in the right direction?

Thanks

CUBE based transcoder is similar to CME transcoder config. Attached is the Config guide..

Thank you, I have followed the document exactly but the transcoder will not register.  Can anyone shed any light on something that I missed before I have to open a case with TAC?

Hi

Change your the version for cme

sccp local GigabitEthernet0/0

sccp ccm 10.1.4.9 identifier 1 version 4.0

put the latest that you can find in the config

Then no sccp , sccp

Your configuration is wrong....

Please remove

dspfarm profile 1 transcode 

codec g729br8

codec g729r8

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

maximum sessions 10

associate application SCCP

what you need is this

telephony-service

sdspfarm units 1

sdspfarm transcode sessions 10

sdspfarm tag 1 XCODE123456

max-ephones 1

max-dn 1

ip source-address 10.1.4.9 port 2000

and the sccp config.

Please remove the dspfarm profile config..

shut down sccp and start sccp again

Actually I just shutdown telephone-service and brought it back up then the transcoder registered properly.  I will let you know if it actually works once we get some test calls placed.

It works perfectly.  Thanks for the help.

Hi aok

The above config that you mentioned is correct

Hi Freeses

Glad to hear that

one mention about trancoding

I believe that in order the trancoding to work properly then you have to remove the voice class from the specific dial peers

Otherwise the transode will not be involved

with show sccp connections you will verify if the trancoding work properly or not

Chrys,

No it is not needed for internal based Transcoder on CUBE. This is similar to xcoding on CCME.

The command is used for external based transcoding where DSP is controlled by a call agent such as CUCM.

In this case, DSP resources are local to the CUBE and do not register with any external device...

Yes I did not change anything and it works properly now from what I can tell.  Since we have only come across 4 numbers where the codec mismatches it doesn't pop up very often so it is hard to catch using a sh sccp connections.  I am going to leave the codec list in place since at this time it doesn't seem to be causing any issues.
