Managing Calls Using IP Telephony
November 2009 218
Incoming IP Calls
Your application can receive incoming IP calls if it uses function calls
from the table below
In this case the application is unaware of the mode of transport
(PSTN or IP):
Channels are either PSTN or IP, but not both. You can not have
PSTN and IP on the same channel. If the first module is IP, then the
first set of channels is IP. If the first module is PSTN, then the first
set of channels is PSTN. The first module defined by lowest module
number, for example, Module 2 gets channels assigned first, then
Module 3 gets channels assigned next, and so forth.
