Configuration manual

• Avaya Aura Messaging — The B5800 Branch Gateway system can be configured to
use Avaya Aura Messaging as its voicemail server when Session Manager is used as the
core SIP router. See Configuring B5800 Branch Gateway to use Avaya Aura Messaging
for voicemail on page 177 for more information. When Avaya Aura Messaging is used
as the central voicemail system, at each branch you have the option to still use the local
Embedded Voicemail or Standalone Voice Mail for auto attendant operation and for
announcements to waiting calls. Note that for this configuration, Embedded Voicemail
licenses are required.
• CallPilot — The B5800 Branch Gateway system can be configured to use CallPilot as
its voicemail server when Session Manager is used as the core SIP router. See
Configuring B5800 Branch Gateway to use CallPilot for voicemail on page 179 for more
information. When CallPilot is used as the central voicemail system, at each branch you
have the option to still use the local Embedded Voicemail or Standalone Voice Mail for
auto attendant operation and for announcements to waiting calls. Note that for this
configuration, Embedded Voicemail licenses are required.
For more information about licensing, see
Licensing on page 16.
The Park and Page feature is supported when the system voicemail type is configured as
Embedded Voicemail or Standalone Voice Mail. Park and Page is also supported on systems
where Avaya Aura Messaging or CallPilot is configured as the central voicemail system and
the local Embedded Voicemail provides auto attendant operation. The Park and Page feature
allows a call to be parked while a page is made to a hunt group or extension. See Configuring
Embedded Voicemail on page 174 for more information.
Branch PSTN call routing considerations
Each B5800 Branch Gateway system can support its own external PSTN trunks. When
deployed in an Avaya Aura
®
network, you have considerable flexibility over where outgoing
PSTN calls should emerge from the network and similarly where incoming calls should be
routed.
For examples of some of the options available, see
Branch PSTN call routing examples on
page 291. The examples demonstrate the following options:
• Centralized call control on page 291 — External calls at a branch site can be rerouted to
be dialed out at another site. This can be done for reasons of call cost and call control.
For example, the central site may have a bulk call tariff for national and international calls
that would benefit all branches.

external calls to the Avaya Aura

Session Manager for onward routing, there may be
