IP Phones on MS ISA Firewall...

[kristiandg]

Good morning all...

Has anyone tried to get IP Phones working on an IPO through Microsoft's ISA Firewall? If so, how did you pull it off. We're having problems with it. ISA server is SBS 2003 box. IP Office is a 2.0.

Thanks...

Kris...

I would certainly be interested in the answer to this question as well!

I'm new to IP office but find out what ports the phone uses and protocol and just open them i think it's H232 is the protocol

Isaserver.org
MCMCSE.com

Goodluck.
