ATA auto answer

Hello-

Does anyone know of any ATA devices that support auto answer? We are trying to make a paging system work, we’ve looked at the Sipuras and they don’t seem to support auto answer.

Thanks

Isn’t auto-answer a function of the analog device that you attach to the ATA, rather than the ATA itself? By this I mean, the analog device should detect ringing voltage and go off-hook.
