Hello,
apparently xlite uses "SPEEX" as the payload name, where RFC 5574 says
it should be "speex", see http://tools.ietf.org/html/rfc5574#section-5.
The SDP RFC says (http://tools.ietf.org/html/rfc4566#section-5):
" In
general, <value> is either a number of fields delimited by a single
space character or a free format string, and is case-significant
unless a specific field defines otherwise."
and for the a:rtpmap attribute nothing is said about case-insensitivity.
In the offer answer RFC (rfc3264) there are many 'case's appearing, but
nothing about case sensitivity...
Nevertheless, SEMS should probably not be so picky about it and treat
the codec identifier as case insensitive. The place to look at in the
source is AmPlugIn::getDynPayload in AmPlugIn.cpp:388, if you want to
have a try on that.

Subject: Re: [Sems] SEMS 1.1.1 and speex
Hi Stefan,
I'm sending you wireshark output and SEMS with debug, as you can see speex is
loaded. when speex is the only codec loaded in eyebeam I get 488 error from
SEMS (scenario 1). when I also enable iLBC in eyebeam, audio is established
(but with iLBC) and in OK response from SEMS I don't see speex (scenario 2).
Thanks a lot
Best regards

Subject: Re: [Sems] SEMS 1.1.1 and speex
Hi,
o Dubravko Caric [10/05/09 20:10]:
Hi all,
I'm trying to use SEMS's voicemail application and XLite just with speex codec.
I see that SEMS doesn't advertise speex rtpmap in SDP although I have enabled
it in sems.conf. I have read that speex isn't supported in versions newer than
0.9.6 but I wolud like to get confirmation on that for version 1.1.1.
speex (narrowband) is supported in sems 1.1.1. Make sure that you have loaded
the speex module; if you start sems with debug loglevel loglevel=3 (or -D 3),
you should see the speex codec to be registered on startup.
If the caller of an incoming call does not have speex in the SDP offer, SEMS
does not add that to the answer; SEMS only answers with the subset of supported
codecs from the offer. Are you sure that speex codec is in the offer? If yes,
could you maybe post an ngrep of the offer and the answer?
