Enterprise Edge 2.0 IP Telephony Configuration Guide P0911590 Issue 02
Private network calls are done by dialing a 4-digit private network DN. For
example, if a user in the west end branch calls a user in the east end branch within
the private network, they dial 6221.
Figure 6 Enterprise Edge and M1 networking overview
If the quality of the IP trunk connection during initial call setup rates as poor,
Enterprise Edge finds an alternate route to complete the call (fallback) based on the
programming definitions in the routing table. In this example, if the quality of the
IP connection is poor during the call setup phase, the call can fail. For an example
of fallback programming, refer to the section, Toll bypass with VoIP telephony on
page 47.
Note: Enterprise Edge IP telephony requires a keycode. After entering the
keycode for Enterprise Edge IP Telephony, perform a warm reset by
following the procedure in the Maintenance chapter of the Enterprise Edge
Programming Operations Guide.
In Table 9 Private and public network routing (West End to East End office), private
network routing information appears in gray. Public network routing information
appears in white.
The Call Managers examine the dialed digits and route the call to the matching IP
address.
