I was wondering what folks prefer as far as equipment goes when connecting a not-tiny amount of analog devices to a Cisco IP environment. We currently have about a dozen ATA186's spread across 3 server rooms, and while I understand the pain it'd take to centralize, one thing I could look at is one VG224 per server room.
Reason's to switch?
The ATA186's aren't exactly the most stable devices, in our experience. I'm having to power cycle at least one of them weekly, but not always the same ones.
Port count vs. cluttter. Having to put a bunch of these non-rack, non-square units somewhere is a challenge for both wiring neatness and space efficiency.
Growth - The ATA186 only powers 2 analog devices. This doesn't scale when you're using them for faxes, conference room phones (that aren't the 7937G), and other analog-only devices in a medium-sized company.
Looking to see if anyone would care to comment on their experience with the VG224 as a more robust platform for enabling analog devices.
Vg248 have been EOL for some time now, and you should be using VG224 instead. VG224 is 24 port analog GW which you can defined with any protocol you want, i.e. SCCP/H323/SIP/MGCP and it simply runs Cisco IOS.
I would defeinitely get these instead of ATAs as they support wider range of applications/features/devices.
Thanks for the responses guys. Seems like there's a lot of positive concensus around the VG224 in regards to flexibility. I'm placing a safe bet that the IOS-backed hardware is more stable/reliable from a day to day perspective than the ATA186's are, as well. Now I just need to figure out how to justify more than one due to the fact that our main office is actually 3 office spaces separated from each other...

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
