I have a Cisco SIP trunk going to Exchange UM on a different segment through a Juniper firewall. If I limit the FW policy to SIP (5060), calls do not go through. I am also seeing a lot of traffic on some hugh UDP ports once the session is initiated. How do I find the range that it is going to use so I can open this up?

Your SIP trunk provider should provide the ports.

My SIP trunk is coming from my Cisco CallManager.

I looked up the ports in Cisco's documentation and added them to the rule. Everything works fine.
