The following task has a new comment added:

FS#435 - crash in parser/sdp/sdp_helpr_funcs.c
User who did this - Daniel-Constantin Mierla (miconda)

----------
The issue was when parsing the line:

a=rtpmap:9 G700

According to the rfc4566, the format of the line is:

a=rtpmap:<payload type> <encoding name>/<clock rate> [/<encoding parameters>]

The clock rate is missing and the parser was not handling properly this case.

I pushed a fix with the commit:

- http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=c842bda9dac46724c58b734d092391c79867f2fb

Needs a bit of testing before backporting, I had not time yet, I will do it soon, but feedback is welcome. Also, there is some room for improvement around that sdp parsing.
