on the FS project guys! I have a specific use case on a seasoned
freeswitch machine that seems to be giving me problems based on SDP,
working NAT configs, and freeswitch. First off, NAT works and my machines
are resolvable by internal IP within the network and publicly via static public
IP. My issue is not a functional NAT issue but how freeswitch
assigns a private or public IP in SDP. I would like to control
IP used in SDP at bridge, so that I can use private IP or public IP
on demand where I want to instead of letting freeswitch insert it based on
config settings.</font></span></p><font color="#000000" face="Times New Roman" size="3">

My scenario is all controlled via configs within freeswitch. All machines
have private and public IPs but specific traffic must pass over private IP and
in other places calls must bridge to another FS machine via external profile
and public IP.</font></span></p><font color="#000000" face="Times New Roman" size="3">

running into SDP IP issues and how freeswitch is handing SDP based on where the
call came from and where it needs to go to. I have spent some time
playing with configs in vars and the profiles around rtp ports and ext-rtp nat,
autonat, etc. I have SDP working how I need it to up to the last step (4
and 5 above) but I cannot get freeswitch to send its internal IP out in
that last SDP session on bridge back over the MPLS. The MPLS only talks
private ip to private ip and FSA is sending its public IP in SDP. </font></span></p><font color="#000000" face="Times New Roman" size="3">
