hi,
I am using freeswitch as proxy server, does freeswitch provide such
SDP masquerading ?
I know this is not the right place to ask this question but still does
any one have any information about it ?
thanx in advance.
with regards

When the nat is detected to be symmetric, (that is we don't receive STUN
replies from a different IP address than the one that was the
destination of the request), it means that there is no way for media
stream go inside the subnetwork. Thus we leave the private address
hoping that the SIP proxy will make some SDP masquerading and relay.
