Description:Hi Guys,

I have setup a DUNDI connection between two Asterisk server 1.6.2.13. I can route calls from two Asterisk when I'm using Alaw codec but when I change it to G.729 it doesn't work.

G.729 codec is working when I'm using an IAX trunk between the two Asterisk, there is no problem only when I'm trying to use it with DUNDI.

When I configure G729 on the first Asterisk I can see on the second Asterisk that the first Asterisk require ALAW codec.



****** ADDITIONAL INFORMATION ******

Below you have the both configuration on iax.conf used by DUNDI:

First Asterisk
[dundi]
type=user
dbsecret=dundi/secret
context=dundi-local
disallow=all
allow=g729

Second Asterisk
[dundi]
type=user
dbsecret=dundi/secret
context=dundi-local
disallow=all
allow=g729




Console log from first Asterisk:

Like you can see the CODEC_PREFS is alaw even if I require G.729

Best Regards.

Do you have a G729 license available?  Also, please upload a complete debug log, not attached it as a note.  It helps keep the issue clean.

We require a complete debug log to help triage the issue.

This document will provide instructions on how to collect debugging logs from an Asterisk machine for the purpose of helping bug marshals troubleshoot an issue:

The usage of codecs between systems has nothing to do with DUNDi. The only purpose of DUNDi is to look up information from remote systems. The authentication, codec setup, etc.. has everything to do with the channel drivers.

I'm closing this as a support issue. Please utilize the appropriate forums such as the asterisk-users mailing list for support with this issue.
