Hi Ray,

Bad news for ya. Still no SIP support for ISA 2004 :(

The first third party to create a SIP gateway for ISA 2004 will do very
well for themselves.

HTH,
Tom

It won't work.  ISA, like most firewalls, does not play nice with the
SIP protocol.  This may have changed in ISA 2004, but you would have to
ask others on the list that have been using 2004 to see if there is any
additional support for SIP yet.  Your best bet is to simply hang a NAT
box infront of the ISA box if you only have one IP, or just hang it out
on the internet if you have to.

Time to get my phone system working for VOIP across ISA.
It really needs to be like a published server, but I cant get the
protocols ironed out.
I cant get an answer on which directions the protocols/ports need to be
configured, send, send/receive, receive/send, etc.
So I thought there would be a way to allow everything going and coming
from the external address to the system itself.

Will it work?
I don't have a DMZ or tri-homed ISA Box.
