Hi everyone,
It appears that in Asterisk version 1.8.10.1 happens the same problem:
asterisk1*CLI> core show version
Asterisk 1.8.10.1~dfsg-1ubuntu1 built by buildd @ yellow on a x86_64
running Linux on 2012-04-24 12:47:04 UTC
The sip calls doesn't work after next log message:
[Aug 22 13:56:44] WARNING[25246] chan_sip.c: Unable to cancel schedule ID
11251269. This is probably a bug (chan_sip.c: stop_session_timer, line
25844).
