I just got my calls working by removing the Record-Route's and then
reinserting then in an order that would according to my topology.
I will need to go back and start from scratch to see if a lot of the other
stuff I did was really needed or not and then update but here is were I
edited the Record-Routes
When the INVITE is coming from my OpenSIPS/Proxy to the Callee I did
if ( is_method("INVITE") ) {
remove_hf("Record-Route");
insert_hf("Record-Route: $(hdr(Record-Route)[2])\r\n", "Via");
insert_hf("Record-Route: $(hdr(Record-Route)[1])\r\n", "Via");
insert_hf("Record-Route: $(hdr(Record-Route)[0])\r\n", "Via");
}
Then when the 180 and 200 are coming from the Callee to the Caller before
the 180 and 200 go to the Caller I did the following
if (t_check_status("180")){
remove_hf("Record-Route");
insert_hf("Record-Route: $(hdr(Record-Route)[2])\r\n", "Via");
insert_hf("Record-Route: $(hdr(Record-Route)[1])\r\n", "Via");
insert_hf("Record-Route: $(hdr(Record-Route)[0])\r\n", "Via");
}
if (t_check_status("200")){
remove_hf("Record-Route");
insert_hf("Record-Route: $(hdr(Record-Route)[2])\r\n", "Via");
insert_hf("Record-Route: $(hdr(Record-Route)[1])\r\n", "Via");
insert_hf("Record-Route: $(hdr(Record-Route)[0])\r\n", "Via");
}
So not sure if there is something wrong with the way OpenSIPS places the
Record-Route ordering when OpenSIPS has multiple interfaces. I am not 100%
sure if what I have done here is right or not but calls are working now.
Any feedback?
