the situation
Asterisk <-- SIP ---> SIPGW <--- SIP Phone
SIP Phone is trying to call asterisk dialplan:
exten => 0224577501,1,Answer()
exten => 0224577501,2,Playback(demo-instruct)
exten => 0224577501,3,Hangup()
however, asterisk 1.2.12.1 (on FreeBSD 6.1) sends back a "488 Not
acceptable here" with a CLI message of
WARNING[162]: chan_sip.c:3529 process_sdp: Insufficient information for SDP
(m = '', c = '')
it seems to be dropping out in process_sdp() because it can't find the m=
or the c=. this is a little odd, so am wondering if this has triggered some
edge case in find_sdp(), get_sdp() or get_sdp_iterate(). i've been poring
thru the code (as the box is remote, and i cant duplicate it locally), but
can't find exactly where in chan_sip.c its borking.
any advice would be much appreciated.
the SIP debug is attached below:
(10.14.32.179 is the SIPGW, 10.14.32.164 is Asterisk)
