10.2.11.2. User Scenarios 
Scenario 1
Call arrives on a trunk at IPDA in Location B (labeled #1 in
the figure below). OpenSape Contact Center requests that the call routes
to an agent extension which is located on the IPDA at Location C,
which routes via PSTN due to payload survivability (labeled #2 and #3).

Scenario 2
Call arrives on a trunk at the IPDA in Location B (labeled
#1 in the figure below). The call routes to the main OpenScape 4000
in Headquarters A via PSTN due to payload survivability to play
a Call Director message (labeled #2 and #3). This call may be subsequently
routed to an agent extension at the IPDA in Location C either
via payload survivability or over the WAN (labeled #4 and #5).

extension (labeled #1). This agent then consults, conferences, or transfers
with an agent on the IPDA in Location C (labeled #2), which routes
via PSTN due to payload survivability.
