[Serusers] PSTN rerouting bug handling CANCEL message

Tue May 4 13:21:32 CEST 2004

Dear all,

I am testing SER CVS head for PSTN rerouting if the
first route has failed like example onr.cfg.  the
problem is the caller cancels the call before the call
is pick up but SER didn’t properly terminate it,
instead it sends to the second route and the third. 
It ends up the callee rings multiple times.   It
didn’t happen in the stable release 0.8.12, but we
would like to usualize the new mysql module connection
pool in 0.8.13 cvs head.  Any one has a solution?
