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?
