Makes sense. What I'm wondering is why the ACK for the negative reply (407) isn't
processed and doesn't seem to result in immediate termination of the first
transaction.
This doesn't happen if I only suspend once. There is no problem in that scenario.
For clarification: do you need to do authentication
two times? Second
time with pv function?
No, the process is basically that I don't know whether I need to do digest
authentication until a preliminary routing query happens (async) first, and if I do, then
I return a 407 challenge from that transaction. I then receive a new INVITE with digest
credentials, and I (async) query for the credentials-info (HA1 of password), and then I
auth_check() the received digest credentials against the info. If not valid, I issue
another auth challenge, and if valid, I continue with route processing (again async).
This sounds like a mess that Kamailio's async stuff wasn't really intended to
support, maybe. I'm wondering if the simplest thing to seed the credentials-info into
Kamailio somehow, e.g. via JSONRPC+htable, so that an async query is not required in order
to obtain it dynamically. I was hoping to avoid that, but maybe there's not another
way to do it?
