Notes:
• If the alternative routing destination is the device itself, the call can be
configured to be routed back to the PSTN. This feature is referred to as
'PSTN Fallback', meaning that if poor voice quality occurs over the IP
network, the call is routed through the legacy telephony system (PSTN).
• Tel-to-IP routing can be performed before or after applying the number
manipulation rules. To control when number manipulation is performed,
use the 'Tel to IP Routing Mode' (or RouteModeTel2IP ini file) parameter,
described in the table below.
• You can also configure the 'Tel to IP Routing' table using the ini file table
parameter Prefix (refer to ''Number Manipulation and Routing
Parameters'' on page 364).
Table 3-46: Tel to IP Routing Table Parameters Description
