Cisco CME with ATA186 using FAX Pass Through mode

This finally worked after getting a bad ATA the first time round that would not respond to https. The first thing you want to do is point your browser to the ATAs IP address (https://IPAddr/dev) and make the following changes:

I configured ATA with static IP address and disabled TFTP.

Network Parameters

Audio Parameters

On the CME I had the fax DID number 5552496501 first get translated to extension 101 using a profile. With the usual suspects of dial-peers and ephones referencing 101, the Fax call is placed to port 1 (determined by the MAC address) of the ATA.
