Chapter 4: Voicemail for G150 Media Gateway
In sub-tending mode, all voicemail functionality is driven by the Communication Manager. In
survivable mode, G150 can operate with Voicemail Pro to take messages on behalf of users
and groups. When connection to an active Gatekeeper is established, Voicemail Pro forwards
all messages to Communication Manager's messaging solution - Modular Messaging 2.0,
Message Networking 2.0 or Interchange 5.4. While in survivable mode, calls are routed to
voicemail as directed by incoming call routing or user/group voicemail settings.
Note:
If the messaging solution is Interchange/Message Networking, additional
Note:
configuration is required after setting up Voicemail Pro. Refer to
with Interchange/Network Messaging
In survivable mode, G150 users have the following restrictions with regards to their voicemail:
NO notification of awaiting voicemail messages.
NO ability to retrieve messages until connection to an active Gatekeeper is restored.
Requirements for Installing Voicemail Pro
SMTP Requirements
Before installing Voicemail Pro, an SMTP server MUST be installed on the Voicemail Pro PC
and tested for sending and receiving messages.
Voicemail Pro uses SMTP to send messages to the Modular Messaging or Message
Networking messaging platform when connection to a gatekeeper is re-established. Voicemail
Pro first attempts an SMTP session with the Mail Server; if this is unsuccessful, it will attempt an
SMTP session with the local SMTP Mail Server. If this is unsuccessful, the voicemail message
will be discarded. To prevent this from happening and to ensure that SMTP messages are
stored until access to the Message Networking/Modular Messaging host is re-established, the
SMTP Mail Server MUST coexists on the same PC as Voicemail Pro.
PC Requirements
For maximum reliability, Voicemail Pro is installed as a service on the following Windows
platforms with a minimum recommended specification of Pentium 4, 2.8GHz or equivalent with
256MB RAM and Internet Explorer 5.5 or newer:
Windows 2000 Server with Service Pack 3 or later and
Windows XP Professional.
Windows 2003 Server.
