Call Manager 6 and Firewall

I have a Call manager 6 pubisher sitting on

network 192.168.0.0/24 and a call manager

6 subscriber sitting on network

192.168.1.0/24. There is a firewall in

between them.

What port(s) should be opened in order

for the publisher to be able to

communicate with the subscriber and

vice versa, in term of call manager

communication protocol?

Thanks.
