[SR-Users] Checking if a reply is part of a forked transaction

[Phil Lavin]

We're already doing some logic before forking and we considered tracking call IDs in a hash table... but your idea sounds interesting (better). I wonder if we can add a parameter to one of the headers in the request. Will explore this tomorrow.


Cheers

It looks like can tell you how many contacts there are before forking.
http://www.kamailio.org/docs/modules/4.4.x/modules/registrar.html#registrar.f.reg_fetch_contacts
and append that somewhere in the request to to the to or via or seomtheing like that....
