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
 UseTFTP=0
 DHCP=0
 StaticIP=172.17.100.9
 StaticRoute=172.17.100.1
 StaticNetMask=255.255.255.0

Audio Parameters
 LBRCodec=3
 AudioMode=0x00150015
 ConnectMode=0x90000404

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.
