VOIP system behind ISA - 19.Apr.2007 2:51:17 AM

Hey,

I am currently running ISA 2006 with 3 nics.
1.Internal
2.External
3.DMZ
In front of ISA there is a Cisco 1812 router with 2m/2m BDSL line for Voip and a Adsl2 line for internal use.

I was wondering where and how would be the best location to place the Voip system so that it will perform well. The Voip also requires access to the exchange server which is a stand alone system located.

Any ideas, tips??

Separate the two DSL lines using two different DSL boxes instead of having them come into one box. The VoIP box needs to come directly into the LAN. It and the ISA would be running side-by-side.

What do you mean by separate the 2 DSL lines?

I dont really want to run the VOIP box on the lan.
Reason:
1. ISA will affect the voice qaulity. right?
2. If ISA fails this means VOIP is down.

What would you guys suggest?
