Subject: App_Conference: SIPp SDP and DTMF mode

Hi,
I'm using SIPp application http://sipp.sourceforge.net/ to generate a SIP
call to open source PBX Asterisk.
Command to call the extension (extension) where the IP is IP address of
Asterisk
[code]sipp -m 1 -d 36000000 -s extension -sf uac_modified.xml IP [/code]
In the configuration file uac_modified.xml there are the following lines
[code]
INVITE sip:[servi...@[remote_ip]:[remote_port] SIP/2.0
Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
From: sipp <sip:s...@[local_ip]:[local_port]>;tag=[call_number]
To: sut <sip:[servi...@[remote_ip]:[remote_port]>
Call-ID: [call_id]
CSeq: 1 INVITE
Contact: sip:s...@[local_ip]:[local_port]
Max-Forwards: 70

[/code]
The call work well between SIPp and softphone (Eyebeam, X-lite), i can see
all the messages in the Asterisk CLI.
If i try to use App_conference application the SIPp user work only without
video support.
Scenarios: there is a conference (DTMF mode enabled) where there are two or
more users when i press a digit to see a generic user, the SIPp user returns
the following error
[code]
sipp: The following events occured:

[/code]
If i disable the video support without the following lines
[code] m=video [media_port] RTP/AVP 115
a=fmtp:115 QCIF=1 CIF=1 I=1 J=1 T=1 MaxBR=4520
a=rtpmap:115 H263-1998/90000
a=sendrecv [/code]
the DTMF mode works well and there is no error.
The problem it's difficult can you help me?
Thank you very much
