[Serusers] Call forwarding domain table error - sr-users

13 Oct 2006


      Hi!
I've seen this problem raised several times, but couldn't quite find an 
answer... I have a problem while trying to redirect the call on no 
answer. Namely I get the following error on the console:
1(10197) use_table(): Invalid parameter value
1(10197) is_local(): Error while trying to use domain table
I tracked it down to this line:
if (!is_uri_host_local()) {  <-----
       if (!isflagset(22)) {
               append_branch();
       };
       route(4);
       route(1);
       break;
};
Funny enough, when I do not use the route_failure block, everything 
seems fine... Does anyone have any idea, what might be wrong? The rest 
of the code involved is given below. Thanks
Regards,
Maciek
