I didn't see too many success stories so I thougt I would add mine. It took me too long to find a modem that worked for what I needed.
What I needed:
Answer phone
Play OGMs
Except DMTF (phone key presses)
Record messages
The biggest issue I had was that the modem I started with didn't except the DMTF detection on a consistent basis - read: it only took 1 out of 10 or so.
Bad modem: Creative Modem Blaster V.92 USB
I thought that since it stated that it was a voice modem it should work just fine. I didn't do enough research first.
Waste of $50.
Good modem: MiltiTech MT5656ZDX-V
Amazon: $94 (6/1/07) - Search on "MT5656ZDX-V"
Disclaimer: I only use it for the above needs. If you need anything more (i.e. outgoing calls, transfers, etc) I don't know if those work. Sorry, this last statement isn't something you want to read when you are looking for a modem that will do what you want. As a user I expected the software maker to help out more here.
I read EVERYTHING NCH and everyone wrote about what modem to get and there wasn't anything consistent.

It would have been nice to have a matrix of functionality vs. modem table to figure out what to buy. Yes, I know modems change, but put a stake in the ground and state: if you want this functionality -> get this modem! Saying users have had good experiences with such and such modem doesn't state that you tested that modem against your software. You do test your software, don't you? What modems do you use that work??????
You really shouldn’t suggest that the user buy modem after modem until they find one that works.
One other point, your support pages state that if you use AT#CLS (Query Modem) and it fails that means that you don't have a voice modem! I may not be a modem expert, but my current Voice Modem does not support AT#CLS in the Query Modem dialog and it works. I was using this Query Modem as the benchmark to see if I had a Voice Modem. Glad I don't believe everything I read.

Good luck!
