Voicemail Pro is pre-installed on Unified Communications Module. However, the following behaviors of a voicemail server installed on Unified Communications Module are different from a standard voicemail server:

• Supported Languages:

  Only the English US and English UK languages are supported for Text to Speech (TTS).

• Accessing Voicemail Pro Server:

  To access the voicemail server running on Unified Communications Module, use the IP address or the DNS name of the IP Office control unit that hosts Unified Communications Module.

• Backup and Restore Settings:

  Backup files can be saved on a USB storage. The available file paths for the USB storage are /media/sdb1 and /media/ sdc1. As the storage space available on UC Module SSD is limited and primarily required for saving call recordings, use a USB storage for the backups.

• Default Debug Level:

  The default general system preference for the Debug Level is Critical.

• Number of Simultaneous Users:

  The maximum number of data channels that can be simultaneously used for voicemail operation is 40. However, if one-X is also enabled on Unified Communications Module, the maximum number of data channels that can be used simultaneously may reduce to 20.

• Storage Space for Call Recordings:

  Voicemail call recordings use an approximate storage space of 1 Mb for each minute of recording. Therefore, the available storage space on UC Module SSD is limited to an estimated maximum of 400 hours of call recordings. Consider this fact if you plan to use the voicemail server installed on Unified Communications Module for centralized voicemail.

• Database actions:

  Database actions are not supported.
