Hi,
I'm trying to set up a Kamailio server as a proxy to forward SIP messages between two trunks, where I manipulate only the INVITE in the following manner:
incoming call:
INVITE +4969123456@server1
outgoing call:
round robin to
INVITE user@4969123456-sip-server2a
INVITE user@4969123456-sip-server2b
INVITE user@4969123456-sip-server2c
Can anyone point me in the right direction? Both SIP trunks are IP registration only. Also, I am aware how strange this is, but the upstream service has decided to interpret SIP in a novel way.
Cheers,
Chris
