One other quick note- If you decide to invest in the 1750, and you are doing
so partially for the Voice capability, please note the following:
1750's come in 3 flavors- 1750, 1750-2v, and 1750-4v.
The 1750 mainboard has a slot for the DSP chip that makes the voice cap.
possible. The base model doesn't have it populated, and these are the most
abundant on ebay. Most of the sellers don't even know if they are selling a
base unit, 2v, or 4v, and unless you contact them and ask them to confirm if
it is at least a 2v or not... don't bid on it. It's more expensive to buy
the DSP separately and add it on then it is to get one off auction with it
already in it. If the auction states that it comes with a 2port FXS/FXO/E&M
port card, still ask the seller to email you a "sh ver" output of the router
in question. Without the DSP, the voice ports won't show up in the sh ver.
All voice parts separate- they'll run roughly the same amt. (275-400USD)
I explain this only because I got burned on my first 1750 purchase- the
seller thought it was a 2v, and didn't open it up to verify. He went off
the memory specs it was displaying and compared that to Cisco Public site
tech specs. The router wound up just having memory upgrades, and no DSP.
Also, the DSP's are in the following fashion - PVDM-4 supports (1) 2port
FXS/FXO/E&M module, PVDM-8 supports 2... 2 channels are required for each
port in simple terms.
Cheers!
Mark
