ports to open (ranges) for voip

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.

Re: ports to open (ranges) for voip

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
