Sasmita,
I think the relevant piece here is not the call to “serialize_branches”, but
how the branches are being created to begin with. Are you using drouting,
dispatcher, registrar, etc? It seems like what is happening is that whatever
mechanism you are using to track the contacts is considering the 486 response
to mean that URI should not be tried again and it is removed from routing. This
behavior is likely configurable in that module.

Hi ,
I know this is a very basic question . Still I need some clarification .
I have 2 contact for same number , When I place a call Openips give that to 1st
if 1st contact reject the call with 486 busy , then opensips try the same call
to the 2nd contact without rejecting the call .
In the next call for same number , opensips tries to 2nd contact if that
rejects the call with 486 it wont try to the 1st contact again . Why is this
happening ?
route{
if (!serialize_branches(1)){
sl_send_reply("500","Unable to load contacts");
exit;
}else{
if (next_branches()){
t_on_failure("1");
}
}
}
failure_route[1] {
if ( t_check_status("404|477|480|481|408|486|50[234]")){
if (next_branches())
{
t_on_failure("1");
route(1);
}
}
}
This is in my config file . i have gone through the doc
https://www.opensips.org/Documentation/Script-CoreFunctions-1-11#toc44<https://www.opensips.org/Documentation/Script-CoreFunctions-1-11#toc44>
but not able to understand properly .
How can I print the internally stored branches on avp ?
Thanks & Regards
