Re: [Serusers] Re: SER CANCEL Processing

26 May 2005

  I am having a similar problem. I am not yet convinced that it is SER
as much as my configuration but if SER does have difficulty processing
CANCEL messages it would be helpful to understand under what
circumstances.

   By the way I have been using t_check_status in a similar way since
v 0.8 code. When I upgraded to 0.9.0, .0 and now .2 the t_check_status
fails to be matched.

Thanks,Steve

 any ideas anyone? seems like SER does not respond to
CANCEL requests and eventually takes the failure
route. 

I have the following in my failure route, but it never
gets hit, since SER does not send the 200 OK back or
pass the CANCEL message forward. log file attached.

failure_route[1] 
{      
    if(t_check_status("487")) { 
     # don't continue on cancellation
     xlog("L_WARN", "OH OH OH\n");
     break;
   }
