Coral Flexicom 280S

I am trying to set up a coral flexicom 280s IP phone for use on Asterisk 1.6

It is using MGCP and appears to be trying to register via MAC address. Has anyone done this?

I have not done this, but would love to know if you were able to get it to work. We have a bunch of 280S that I would like to use with an Asterisk system, but I’ve been told since they don’t support SIP it’s not an easy setup to configure.
