Hello everyone,
I'm running into a issue, where I'm trying to implement parallel
forking, so basically on incoming calls from gateway, I want to then
Re-Invite, and send out the calls to multiple destinations, I am currently,
using avp_db_query to grab the sip uri's and throwing them into an avp list,
and avp_pushto("$ru", "$avp(i:1)/g"); This all works fine and good, invite
comes in, and then sends Re-Invites, however, there seems to be some kind of
race condition where, it is not properly processing all of the Re-Invites,
to fork the calls out, and basically one of the calls picks up 183 early
media, then 200 OK, and terminates the other branches / calls. However they
were never executed / no phone was ever picked up. Any ideas on what I'm
doing wrong, or what could possibly be happening? Any help is appreciated,
thank you.
I am using OpenSER v1.1.1, example sipcap posted below:
