Cisco SIP through a Firewall

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?

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

Your SIP trunk provider should provide the ports.

My SIP trunk is coming from my Cisco CallManager.
