Voicemail Pro TTY Prompts
TTY is a method of sending and receiving text messages within the speech path of telephone calls. The text is entered and displayed through a TTY device connected in parallel with the user's normal phone. Due to its widespread usage and support it has become the standard used by devices for the hearing impaired.
Voicemail Pro 1.4 supports the addition of TTY prompts for Intuity mode mailbox access, that is leaving and collecting messages from a mailbox. Caller's with a TTY device can see the TTY prompts and leave TTY format messages. The mailbox user, also with a TTY device, can collect and display those messages by following TTY prompts.
The TTY device and associated analog phone (linked either by a pass-through port on the TTY device or a telephone splitter) are connected to an analog extension port (POT) on the IP Office system. During calls the TTY can be used to display and send TTY. The analog phone can be used to send dialing digits and provide a speech path during calls.
Installing Voicemail Pro TTY Prompts
The required TTY prompts are now selectable from the list of Speech Supported language options during the installation of Voicemail Pro.
Changing the User Locale
This is the simplest method as it requires no customization of the user's mailbox operation.
In IP Office Manager, click on to receive the system's current configuration.
Click on User to display the list of users.
Double-click on the user for whom you are setting up TTY mailbox operation.
On the User tab, enter TTY in the Locale field.
Click on OK.
Click on to send the configuration back to the system. If user locale was the only change made, then select a Merge Config.
The locale setting tty is not actually recognized by Manager. Therefore all aspects of the user's telephony operation on the IP Office will default to the system's locale setting (System | System | Locale). However, the user locale setting is transferred to the Voicemail Pro server during mailbox access and so will alter the prompts provided.
In order to access their mailbox, the user should dial *17 and then take the analogue telephone handset off hook. Once connected, they will see TTY prompts on the TTY display.
TTY requests such as "Press 1 for …" should be handled by dialing from the keypad of the telephone. TTY messages followed by GA (go ahead) require text typed from the TTY device.
