Two-Way Acknowledgement
The Voice Notification module can be configured to allow users to quickly acknowledge alarms. With the Two-Way property enabled, the notification is sent out a response code in the message. The user simply replies with the response code and the alarm will be acknowledged.
Custom Notification Messages
The High-Quality Text-to-Speech engine allows you to customize the alarm message the user hears, so you are not limited to a number of pre-recorded messages.

Audit Log Integration
The Voice Notification module can be configured to log successful message delivery and user acknowledgement into any connected database. Once recorded, a simple query will return all notification activity.
Multi-Language Support
Write your messages in any of the provided languages. A list of the available languages can be found on the Voice Languages page.
This module requires the Alarm Notification module and some SIP-compatible VoIP service, such as your office VoIP server or an IP Telephony Gateway appliance to bridge to a standard phone line (not included).
Examples of a IP Telephony Gateway appliance are: Atcom IP04 (the number indicates the phone lines, Ignition can only use 1 line at a time), Grandstream HT-503, GXW410x (It is the FXO port that connects to the phone line).
