[Freeswitch-users] Freeswitch as a pseudo-proxy

FreeSwitch can handle NAT traversal and hide topology so you can do things
like header cleanup, codec normalization, like a full blown SBC or you can
ack as a semi-topology hiding (no media) sip only b2bua... So you hide where
the sip messages are going but stay outta the media path...

As far as passing thru other sip requests IE: registrations or subscriptions
going to another box etc... That's not really something at this time
freeswitch can do...
