I have about ten ATA-187's currently deployed around my organization, and a small pile of them on the shelf left by my predecessor. I'm going to need another ATA deployed soon, but with the 187 EOL for a long time I'm looking for a suggestion on its replacement.
More to the point, is there a reason I should upgrade the deployed 187's that are generally working fine?
Are there any security implications in using a device that won't see any firmware updates? Same question also applies to our older phones, such as 6945 and 8961.
My IT management is big on security, I have good budgets, and they generally don't care for devices that are EOL. The 187's work just fine otherwise.
