Hunt Group Voicemail

From firmware versions 3.5.7 and onwards, Hunt Groups can be used as a shared voicemail system which allows all members of the Hunt Group to listen to or delete voicemails received by the Hunt Group.

This is configured by selecting "Voice Mail to This Group" as the Overflow Rule for the Hunt Group.

When listening to voicemails, group voicemails will be prefaced by a "Group Message" prompt.

If the Voicemail to Email functionality is configured, the PBX will send emails to both the Hunt Group email address and the email addresses of all members of the group.

The Voicemail notification light (MWI) will be lit for all members of the hunt group until the message is listened to or deleted.

When the message is deleted, it will clear on all extensions.

Listening to Voice Mail remotely

It is possible to set up the IPPBX so that people can dial in to the PBX system and access voicemails from firmware version 3.5.7 and onwards;
This requires a SIP Alias / DDI number, which is configured under IPPBX - Trunks - SIP Trunk - Alias List.
When inputting details for an alias number, set the Answer Mode to "Forward To Voice Mail System".


Any calls into this number would then work in the same way that dialling 889 would with an extension registered to the PBX system; it will request the extension number then the password, at which point the voicemails for that extension can be listened to or cleared.

Voicemail to Email

The PBX system can send an email with the voicemail file as an attachment - this works best if the call is received as G.711 codec because most computers / devices cannot playback G.729 codec voicemail files.

This is configured from the IPPBX - PBX System - Voice Mail/Virtual FAX Configuration page; tick the "Send Voice Message by Email" option for the PBX to send voicemail emails in this section:

The authentication details for the SMTP server can be configured under the Email Server Setup section. The Voicemail to email system supports only normal / unencrypted SMTP with current firmware.

Enable the “Prefer WAN interface” option if the SMTP traffic needs to go over a specific WAN interface. If it needs to go over the LAN or doesn’t need to be specified, leave the option unticked.
