Using an ATA with an Analog Phone

[WesleyC9288]

Why is it that we can't connect an analog phone to an ATA and use it with Zoom Phone but we can use an ATA for fax? That's what I was told by the sales rep.

That's incorrect. Zoom is not monitoring each ATA device to verify if it's generating a fax tone vs plain jane audio for a voice call. I've used Cisco ATA's for POTS on desk phones no issue.

What's POTS?

And why would Zoom say that ATA support is only for fax?
