How to create/configure a line for hearing impaired device

[avi777]

Having problems configuring an Ultratec Uniphone Combination TTY and Telephone device for a customer that has an employee
with hearing impairment. Configured the line as analog since the device connects via regular 2-wire analog line according to the
manual. Has anybody out there been confronted with or have experience connecting such device. My platform is an Avaya Aura CM6.0
I have attached the equipment manual the customer is using.

Thanks.

whats the problem?
I'd imagine configuring it like a basic analog phone would be enough.

What, specifically, isn't working right?
