[SR-Users] Kamailio + RTPEngine SIP Proxy...

[Richard Edmands]

So what you'll want to look into is Freeswitches registration data for
those users and then figure out how to have Kamailio re-write that in
a way that Freeswitch will store and send back out using it.
Perhaps your freeswitch config is still doing some NAT processing and
coming up with incorrect results?

Still haven't found the motivation to run a Freeswitch box myself yet,
maybe one day.
