[SR-Users] How to Absorb First Leg Re-Invites when no Response from Second Leg Invites

Yes, retransmissions of initial INVITE from Carrier. Makes perfect sense, I understand now. 

 Thanks Gentlemen!


Reinvites are in-dialog requests; they would only be sent within the
context of an established dialog (2xx response, end-to-end ACK, the
whole works).

Perhaps what you are referring to is not reinvites but retransmissions
of the initial INVITE?

If so, have a look at this option:


in concert with something like this:

   failure_route[...] {

       # The scenario you're after.

       if(t_branch_timeout()) {
           t_reply("503", "Service Unavailable");
