Hello,
Can anyone tell me which ports (TCP and UPD) to open on the firewall when you have ip phones and ip communicator behind it?
This just to squeeze down the range a bit.
Thanks for your help.

TCP Port 2000 for Skinny
UDP Port 69 for TFTP
UDP port for DHCP
UDP port 16'000-32'000 for voice
And for the web-services you need port 80
Try this link: you can see here which ports are used for what on the CCM
