Voicemail Pro Customization
An alternative to setting the user locale as TTY is to change the users language setting within the Voicemail Pro call flows for that user.
Simple Mailbox Customization
The Select System Prompt Language action can be used to change the prompt language used by subsequent actions in a call flow. Once the TTY Maintenance Patch has been installed, TTY is one of the selectable languages provided by the action.
In the simplest form, a Select System Prompt Language action set to TTY, would be added to the user's Collect start point and followed by a Get Mail action.
Similarly a Select System Prompt Language action set to TTY, would be added to the user's Leave start point and followed by a Leave Mail action.
Complex Mailbox Customization
If required, more complex call flows can be configured. For example, the call flow below allows callers to press * to receive spoken language prompts or to wait a few seconds for the timeout and then receive TTY prompts.
In this case messages are left in the same mailbox, but callers can select to have spoken prompts or default to TTY prompts.
For hearing impaired users who cannot handle spoken messages, the call flow for callers who select spoken prompts could have place those messages into an alternate mailbox of a hearing user. These could then be collected and transcribed for the user.
