Branch PSTN override
In the example provided in
Centralized call control on page 325, we configured the branch
system so that all national and international calls go to the headquarters site for routing to the
PSTN. There may occasionally be scenarios where a particular number needs to override this
and be dialed via the branch system's own PSTN trunks.
One example is the Modular Messaging PSTN number that can be configured for access to
voicemail when the branch's Avaya Aura
®
Session Manager line is out of service. Another
might be to provide a maintenance number to the headquarters site to report suspected loss
of the Avaya Aura
®
Session Manager line connection.
