Firewall between Unity and CallManager

What ports need to be opened in a PIX firewall to allow the TSP to communicate. A pix is located between two network segments. The one segment is the CallManager's, the other segment is exchange servers and unity. This network is firewall/security crazy and this network topology will not be changed...

Re: Firewall between Unity and CallManager

Unity is basically the same as an IP Phone to CallManager.

SCCP uses port 2000 (TCP) for IP phones and Unity by default but is it configurable.

Ports 16384 through 32767 (RTP/UDP) are used for the voice stream and this is not configurable.
