asterisk users - Sep 2004 - Speex/ILBC buggy with * 1.0 and X-Lite/Pro?

I'm playing with codecs at the moment and have found some notices errors 
when x-lite/pro connects to asterisk with Speex or ILBC. Initially I was 
getting garbled sound, but after changing magic number for both codecs 
to 97 (as per 
http://www.voip-info.org/wiki-Asterisk%20phone%20xten%20xlite and 
http://bugs.digium.com/bug_view_page.php?bug_id=0000918) I was able to 
get normal voice. BUT, Asterisk console (run with asterisk -vvvvvvc) 
started to show the following messages:

1. All codecs disabled in X-Lite/Pro except iLBC and Speex or only Speex:

Sep 27 12:15:45 NOTICE[135169024]: rtp.c:420 ast_rtp_read: RTP: Received 
packet with bad UDP checksum

packet with bad UDP checksum

Keeps outputting the notice till hangup. sip show channel # shows Speex 
as the codec used.

2. All codecs disabled in X-Lite/Pro except iLBC:

X-Lite/Pro shows Speex used even it is disabled.

Despite out of buffer space warning, voice is still ok.


I'm using asterisk CVS-HEAD-09/26/04-02:10:24
