"Best" ATA for fax machines?

[dg]

Good day, folks,

I'm interested in putting several fax machines on our 3300 with ATA's. We tried this before using ports on the analog cards over SIP and it was a miserable failure. However, now we're on a PRI, so I'm fairly certain faxes should work properly. I'm also thinking that ATA's would be more flexible in that I can move them around with existing ethernet ports rather than having to reroute phone wires. What models of ATAs are officially supported for the 3300? Are the Cisco 112/122's covered? Grandstream? Any others? I'd like to hear experiences from folks that are using any ATAs for faxing.

Thanks in advance,

The Mitel branded ATA's, which are MediaTrix units we've had a tone of success with.

Personally, really like the Grandstream units, especially in high-density deployments, but have also successfully used Audiocodes MP-1xx series.

Mitel has a list of tested, approved SIP devices in their SIP Center of Excellence document.

We use ports on analog card with PRI in UK quite successfully. We also route them down networking quite happily using the correct dongles.
