Got it working - for some reason, when I broke the ISA rule into 2 different rules (one for 5080 and a separate one for 30000-31000) - it started working. Thanks for the help.

Look for udp traffic 10000 - 31000 , tcp 5060, udp 5060, tcp 5080, udp 5080 Start with that I guess... Or just target all traffic to/from the IP addresses of your ITSP.

Yes - I can enable logging on the ISA server to see what is going on - but I need to be fairly specific on what I'm looking for - we have a lot of traffic going thru there. ________________________________ From: Picher, Michael [mailto:[email protected]] Sent: Sun 9/27/2009 2:23 PM To: Nathaniel Watkins; [email protected] Subject: RE: Sip Trunk - one way audio? Do you have any way to capture traffic at the firewall? Mike From: [email protected] [mailto:[email protected]] On Behalf Of Nathaniel Watkins Sent: Sunday, September 27, 2009 2:23 PM To: [email protected] Subject: Sip Trunk - one way audio? All I finally decided to try setting up an itsp and do some sip trunking. I am running the latest .iso 4.02... - I setup a callwithus.com account and made the necessary holes in our ISA firewall (udp 5080 and the 30000-31000 ports - I am not at the office - and think that is what I read). I am registering to callwithus.com and am able to make outbound calls. Audio however is only going one way. From my polycom 650 - I dialed my cell phone. I am able to hear audio on my cell phone - but nothing on my polycom phone. The polycom phone does not even ring. I do allow all outgoing traffic from our sipx box. Any idea on what I've neglected - or are the logs required to troubleshoot? I am assuming there is something inbound that is being blocked - but have no idea what it would be.
