Hi Everybody,

I'm using Ekiga for a corporate project.
Using Ekiga I connect to a local server in my company which 
runs voice applications. I want to use Ekiga to test these 

I use sip addresses like 123 at etc.
The server is unable to understand the DTMF PayLoad because the codec
used by Ekiga is 101 and the one supported is 96.

I receive the following error when i run :

ekiga -d 2 -c 123 at

2007/09/21 14:28:12.849   0:11.431        SIP Transport:a2de7c8 SDP
Media attribute rtpmap found for unknown RTP type [pt=96]

Following is the server's log:

I don't know much about codecs. 
Is there a version of Ekiga which can help me solve this problem?
Currently I'm using Ekiga 2.0.2 on Gnome 2.16.
Ekiga was a part of the CentOS 5.0 distribution.
