I have a call coming from lync to FS... then I bridge the call to my gateway... it's the INVIT on the gateway to my ISP/VOIP provider where I have at private IP address in the INVIT... I'm trying to set external IP of my firewall... SIP is working fine.. but not media Regards Martin From: Adam Kelloway [mailto:adam.kelloway@newpace.ca] Sent: 25. april 2012 18:02 To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] INVITE ext-rtp-ip not set in FROM and SDP So this INVITE originates from your Lync Srv? When FreeSWITCH is used as a server, I believe it would detect that it doesn't need to use ext-rtp-ip because the INVITE originated inside the network. I have never used FreeSWITCH as a proxy, however. Have you checked out the wiki? http://wiki.freeswitch.org/wiki/Special:Search?search=SBC&go=Go On 25/04/2012 6:46 AM, Martin Soerensen wrote: Hi all.
