WHAT IS IPTTY?
ipTTY (sometimes referred to as TTY over IP or TTY over VoIP) is engineered to allow TTY communications using existing telephony infrastructure. The program communicates through IP and uses standard session initiation protocol (SIP). ipTTY enables virtually every user on your telephony network to communicate with customer TTY machines or the Text Relay Service (TRS), without the need for expensive analog lines or FXS gateways. Additionally ipTTY supports audio for hearing and voice carry-over and real-time-text via RFC 4103; the future in real time text communication.

HOW IT CONNECTS TO YOUR VOIP/HYBRID PBX
If your VoIP/Hybrid PBX supports SIP, there is no need for additional equipment. This is because ipTTY connects directly to the phone system via SIP. When setting up a user with ipTTY, the telecom admin configures a 3rd party SIP extension on the phone switch.
ipTTY is ready for the Enterprise. ipTTY comes in an MSI file that can be setup for silent installs across the enterprise. The ipTTY install also comes with a license file. This means that your end users will not need to go through a product activation process. Lastly, at the discretion of the customer, the ipTTY install can be customized to include configuration information which enables the telecom admin to do the majority of the configuration of the application prior to the end users running it for the first time.
