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.
