STIR/SHAKEN - sr-users

Thanks!

This is what I've got so far:

1. Kamailio invite -> NSS
2. NSS 302 -> Kamailio
3. Kamailio ack -> NSS

I can see the identity header on the 302 response in my onreply_route. How
can I replay the same invite from step #1 with the identity header I get
back in step #2? Should I be doing something with a transaction on step #1,
maybe start a branch that goes out to NSS and when it comes back resume the
transaction (these are all words I've heard smart people say, but I don't
fully understand them...).

Any pointers would be greatly appreciated, thanks!

  These are all valid approaches, depending on
preference. Catching 302s and
 extracting exactly the desired info might be easier with Kamailio, so I
 suppose, ceteris paribus, I'd recommend the first one.

 Dispatcher is a great approach!

 Hello,

 We're attempting to add identities to our invites. I believe we want to  send
our invites to the NSS, and it'll reply with a 302'd invite with an
 identity header. We currently use FreeSWITCH for dialplans and media and
 Kamailio as our SBC.

 Should we be trying for something like: FreeSWITCH -> Kamailio -> NSS  (302)
-> Kamailio -> PSTN

 or would it make more sense to do: FreeSWITCH -> NSS (302) -> FreeSWITCH 
-> Kamailio -> PSTN

 Assuming we wanted Kamailio -> NSS, is using dispatcher the right  approach? We
currently use it for our two Kamailios and our FreeSWITCHs.
 We're going to have two NSS servers, one for failover.

 Any thoughts would be greatly appreciated, thanks!
