Questions about using two VG200 gateways back-to-back

First off, please forgive me as I'm very new to Cisco products, and came into some information that might lead me to believe the VG200 product will do what I need.

I have a private microwave IP-based network and the need to transport bi-directional audio across it. This is for two-way radio communications (RoIP).

What I'd like to know is, can two Cisco VG200's equipped with VIC-2E&M cards be set up to work back-to-back (what goes in one on one end of the link comes out of the other on the opposite end and vice-versa), or do I need to have a Call Manager in between them?

Any help would be appreciated. I realize I can only buy these aftermarket, but I don't want to buy them if they won't do the job.

Our IT specialist is familiar with programming Cisco products, but he's never worked with the VG200 specifically. Since I'm heading up the project, I'm tasked with asking all the questions.

Lastly, if these gateways can be configured "back to back", what's the latency like as far as the audio is concerned across a dedicated 10MBPS network with nothing else but these devices on it? Is it pretty much instantaneous, or is there some significant delay?

Any help is most sincerely appreciated.

Chris,

     Paolo is right. I understand you wanting to spend as little money as possible just to make sure it works. For that very purpose, you can use a pair of 2651XM's. You can get those for less than $50 on Ebay these days. However, once you verify it works (blinky lights and works), purchase yourself a pair of 2801 or even 2811. Those are around $400 these days on Ebay and will outlast the 2651's. Not to say the 2600 series isn't still good, but they are VERY old and really should only be used in a lab environment.
