the 302 am I supposed to
reroute the call in failure route the same way I would, say, a 503 error

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.
