[asterisk-users] SIREN14 call setup and record/playback

I've got a fresh (1 day old) svn trunk release SVN-trunk-r225360 of Asterisk
and I'm trying to get it to accept a SIREN14 call from Polycom's softphone.
Having trouble with SDP negotiation, I want to only allow SIREN14 and
nothing else.  I also want to record and playback files, any tips on what
the Record function parameters should be?

In sip.conf I have:

disallow=all                   ; First disallow all codecs
allow=siren14                ;  Is this the right name?


And the INVITE comes from the Polycom softphone with an SDP of:

...
User-Agent: Polycom VV 8.0.4.4035.
...
m=audio 12386 RTP/AVP 99 98 97 102 101 103 9 15 18 0 8.

max-br=1025.
a=rtpmap:34 H263/90000.
a=fmtp:34 CIF4=1;CIF=1;


Thanks in advance for any tips,

Tom
