can you capture the packet sent over the datagram and
paste it here? Since I
do not have a sems instance now, I am not able to test it without a sample.
Here is the capture:
http://sip.antisip.com/call-sdp-with-quote.pcap
The line where the problem shows is this one:
a=fmtp:98 mode="6,any";cng=on
The above comes directly from the newest rfc ;)
http://www.ietf.org/rfc/rfc5574.txt
Those " can appear in any a att-value where: (rfc4566)
att-value = byte-string
byte-string = 1*(%x01-09/%x0B-0C/%x0E-FF)
;any byte except NUL, CR, or LF
I'm now using sipctrl plugin with sems to avoid the issue! So
I'm not in a hurry for the fix...

Some may know that speex payload format was
published
as an rfc last week and the last change before publication
was the addition of the "quote" for the mode parameter.
a=fmtp:98 mode="6,any"
It's pretty clear that the '"' character is messing up the mi_datagram
exchange.
