invalid SDP -- refuses to relay RTP

[bmartinAEQ]

1. Brekeke Product Name and version:
Brekeke SIP server 2.1.6.6

2. Java version:
Version 6, update 5

3. OS type and the version:
Windows XP SP2

4. UA (phone), gateway or other hardware/software involved:
UA is propiertary audio system

5. Select your network pattern from
http://www.brekeke-sip.com/bbs/network/networkpatterns.html
(for test purposes)

6. Your problem:
Whenever I try to do RTP relay between our UA and anything else I get a 603 (Decline) and the logs tell me "Invalid SDP". The UA has gone through intensive interoperability tests with other UA and softphones (Kapanga, X-lite). Below you can see the INVITE packet. I can only presume that when parsing the m fields, Brekeke does not accept specification of the number of channels: audio 5006/1 RTP/AVP 8. Is anybody aware of this? Or am I missing something about ... ???

Thanx

Hi bmartinAEQ,

The current version of Brekeke SIP Server doesn't support such a SDP format.
m=<media> <port>/<number of ports> <transport> <fmt list>

But the next release will support it.
