Configuration manual

5. To enable the local B5800 Branch Gateway system features for Embedded
Voicemail auto attendants and announcements, in the Use embedded for AA and
Announcements drop-down box, select the appropriate embedded voicemail. The
announcements are those that the callers hear when the call in on hold.
Note:
You must also enable the announcements. Do this by selecting the check box for
Announcements On which appears when you select Hunt Group >
Announcements tab and Users > Announcements tab.
6. In the MM Number field, enter the extension number configured for mailbox access
to the Modular Messaging system. Note that this number is automatically routed via
the active Avaya Aura
®
Session Manager line. It does not need to be routed through
the normal branch call routing.
7. In the MM PSTN Number field, enter the PSTN number to which you want to reroute
attempts to access mailboxes when the Avaya Aura
®
Session Manager line(s) are
out of service. (This field is optional.)
This number needs to be a valid DID number from the branch to the Modular
Messaging system. When calls to access voicemail are routed by this method, the
caller will be prompted by Modular Messaging to indicate the action they are
performing (leaving or collecting messages) and the target mailbox.
Depending on the call routing being used by the branch system for external PSTN
calls, you may need to do additional configuration to ensure that this number is
routed via a branch PSTN trunk. See
Modular Messaging and Avaya Aura
Messaging PSTN Fallback on page 180 for more information.
8. In the Maximum Record Time field, use the up and down arrows to set the
maximum recording length in seconds for recorded announcement and auto
attendant prompts.
Note:
You can set a number in this field only if you selected one of the two embedded
voicemail options in the Use embedded for AA and Announcements drop-
down box.
9. In the VoiceMail Ports field, use the up and down arrows to set the number of
licensed voicemail ports.
Note:
You can set a number in this field only if you selected one of the two voicemail
options in the Use embedded for AA and Announcements drop-down box.
Modular Messaging over SIP requires SIP Trunk Session configuration and uses
SIP Trunk Sessions licenses.
10. Accept the default setting (on, that is check box is checked) for Enable Voicemail
Instructions Using DTMF.
