Not being able to reproduce this, I really need some debug information to
move on. Please do the following :
- set the 'debug' option to 'yes' in your jabber.conf file ;
- check your /etc/asterisk/logger.conf file and make sure your 'console'
entry contains a 'debug' attribute, ex :
console => notice, warning, error, debug, verbose
- run asterisk with the debug option (-ddd).
Also, line 1283 in my revision of res_jabber.c does not match with yours.
What's the output of the following commands (first cd to your Asterisk
trunk source) :
- svn diff res/res_jabber.c
- svn info res/res_jabber.c
