Re: [Kamailio-Users] LRN routing - 302 sip code

One of our carriers gives us an option to check LRN routing via SIP before we attempt to send out a call. Our request will go out as a regular invite, then we'll get a 302 return code back, with the result contained in the header.

My question is, how exactly is the flow of this kind of call supposed to work? I thought I could do a regular failover, but that doesn't work. Does anyone have a suggestion?

- The proxy routes the INVITE to the carrier. - The carrier replies 302 with the real destination in "Contact" header. - The proxy does recursion for 302, extracts the URI from the "Contact" header and generates a new branch to that URI.
