We have a customer that currently utilizes a DCS100 with 7, 12, and 24 button phones. Not all phones have the Display.

Does anyone know if these phones will be supported if the customer upgrades to an OS7200? Any limitations or issues? I recall reading a post that the phones need to be 1.7 but so far, that statement isn't backed up with anything from Samsung. There appears to be some confusion on the OS7200 versus the OS7400.

For non-display phones, how can the version number be determined?

Cheers
