So im using Kamailio as a load balancer and proxy
in-front of a few Freeswitch boxes.
Im not going to use RTP Proxy, as my FS boxes will be
public on the internet ( Direct RTP connection is fine ).
I want ALL SIP to go via Kamailio, but the issue im running
into is that the SIP Contact header has the FS IP address in
it in some cases. ( 180's etc )
Every bit of documentation I can find about re-writing the
Contact header is geared around NAT, and thats not what im
trying to do here..
Can anyone give some pointers on how to basically topology
hide the FS boxes on the SIP front but leave their IP in the
SDP.
im going to have the firewalls setup so the SIP Can ONLY
come from kamailio, so its quite important I get this all
right.
Any pointers would be appreciated.
Thanks
Jay
