[Serusers] simple blind call forwarding needed

SER Users: Thanks in advance for any help! I am running ser 0.9.6 and have a relatively simple cfg file. I have only four (4) digit extensions, no PSTN, no NAT and I do not care about authorization so my config file is basically the Hello World ser.cfg with my system parameters and a few statements in route that allowed me to create standing conference rooms and an echo application with sems. Now I need to implement call forwarding and I have been able to setup the MySQL ser usr_preferences table per chapter 10 of the 'SER - Getting Started' and the 'mySQL newbie? Problems with mySQL and SER?' documents. After adding the call forwarding functionality discussed in chapter 10 inside my config file any number dialed to a SIP device rings busy. All SIP devices register and can call the conference rooms or the echo application but they can not call each other. I will spare you my WireShark logs but can provide if that is needed. I'm looking for trouble shooting suggestions. Is there a way to print to the std i/o from inside the cfg file? This is the first time I needed to handle the INVITE message so I've included my INVITE Message Handler and the Call Forwarding Handler that I added for this effort: ... if (method=="ACK") { route(1); break; } if (method=="INVITE") { route(3); break; } if (method=="REGISTER") { route(2); break; }; ... route[3] { # ---------------------------------------------------------------------- # INVITE Message Handler # ---------------------------------------------------------------------- # Note: We are using this fuction only as a hook into the # blind call forwarding feature. Simply want to change the # R-URI and relay the message. if (avp_db_load("$ruri/username", "s:callfwd")) { setflag(22); avp_pushto("$ruri", "s:callfwd"); # Would love to do a printf here to see if this code is being hit!!! # Wireshark shows INVITE messages are being sent. # debug/printf("\n\n****** Inside route(3) ********\n\n"); # At this point the a blind call forwarding record was found and the # new destination was written in the R-URI. # DEBUG: try just calling route(1). # route(1); # Send to Call Forwarding Handler route(6); break; }; route(1); } route[6] { # ---------------------------------------------------------------------- # Blind Call Forwarding Handler # # This must be done as a route block because sl_send_reply() cannot be # called from the failure_route block # ---------------------------------------------------------------------- lookup("aliases"); if (!is_uri_host_local()) { if (!isflagset(22)) { append_branch(); }; route(1); break; }; if (!lookup("location")) { if (uri=~"^sip:[0-9]{4}@") { route(1); break; }; sl_send_reply("404", "User Not Found"); break; }; # DEBUG: There are no alias' and we are not sending calls to other # networks. We may just need to call route(1) and not this # function. route(1); }
