asterisk users - Jan 2004 - X-Lite & Asterisk: Speex & iLBC not working?

This seems to have been reported before, but I've seen no resolution:
http://lists.digium.com/pipermail/asterisk-dev/2003-August/001470.html
http://lists.digium.com/pipermail/asterisk-users/2003-August/019091.html
http://lists.digium.com/pipermail/asterisk-users/2003-October/024472.html

When forcing use of Speex, no sound comes out at all (Speex-1.0.3 on the 
Asterisk server)
When forcing iLBC, there is some very garbled noise, but nothing 
intelligible.

Sniffing the packets, I can see that X-Lite & Asterisk have chosen 
differing 'Payload type' numbers:
X-Lite:
a=rtpmap:97 speex/8000
a=rtpmap:98 iLBC/8000
Asterisk:
a=rtpmap:97 iLBC/8000
a=rtpmap:110 SPEEX/8000

According to the Speex RFC, this is acceptable:
http://speex.org/drafts/draft-herlein-speex-rtp-profile-00.txt
"Dynamic payload type codes MUST be negotiated 'out-of-band' for
the
assignment of a dynamic payload type from the range of 96-127."

I'm wondering whether the system is at all case sensitive?
 From the RFC:
"When conveying information by SDP [4], the encoding name SHALL be
"speex"."

NB Ethereal shows payload-type as being 97 when X-Lite reports iLBC & 
110 when X-Lite reports Speex, so the Asterisk numbers seem to 'win'.

Any light shed on this would be great.
Whilst GSM is ok, it would be great to leverage the power of Speex :)

Thanks a lot,
Fran.

If this may be of any use:

I'm not an expert but I did the test with the FWD soft phone from X-ten and
iLBC & SPX don't work.
Asterisk wasn't between the connections. Just x-lite and fwd (who is an
Asterisk Server?)
The soft phone makes the connection but I can't hear any sound.

Answering my own question :)

There's a .reg file that can fix the X-Lite clients' interop with
Asterisk:
http://bugs.digium.com/bug_view_page.php?bug_id=0000918

I have updated the Wiki:
http://voip-info.org/tiki-index.php?page=Asterisk+phone+xten+xlite

Cheers,
Fran.

On the flip side, I have tried the registry fix with X-Lite build 1101
against Asterisk 0.7.1 (Debian/Unstable package), and it works (at least for
speex)

Asterisk 0.7.1 from Debian/Unstable
Win2K
X-Lite build 1101
