TCP UDP Ports

[raymk]

Good morning,


I have been tasked with providing some ip phones at our remote office i have set up all the routing and end to end connectivity exists from a ping perspective.



Could any one advise on what ports i would need to have open on the firewall to allow a 5312 ip phone to register with our 3300 controller and to make and recieve calls.

Any advise greatly appreciated.

no nat in the path right?

if so, 6800-6802/tcp, 3888-3999/tcp, >1024/udp
