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...

Tks
Aymeric
