Dialogic Corporation

The IP Media Call Control Library (IPM CCLib) performs the following tasks:

processes Dialogic

®

 Global Call API CCLib commands for the opening, closing, and timeslot 

routing of IP media devices

configures QoS (Quality of Service) thresholds

translates QoS alarm events to Dialogic

®

 Global Call API alarm (GCAMS) events

The IP Media Resource processes the IP Media stream. It performs the following tasks:

encodes PCM data from the TDM bus into IP packets sent to the IP network

decodes IP packets received from the IP network into PCM data transmitted to the TDM bus

configures and reports QoS information to the IP Media stream 

This section includes information about device types and usage:

 

 

 

When using Dialogic

®

 Global Call API with IP technology, a number of different device types are 

used:

IPT Board Device

A virtual entity that represents a NIC or NIC address (if one NIC supports more than one IP 
address). The format of the device name is iptBx, where x is the logical board number that 
corresponds to the NIC or NIC address. See 

for more information. 

IPT Network Device

Represents a logical channel over which calls can be made. This device is used for call control 
(call setup and tear down). The format of the device name is iptBxTy, where x is the logical 
board number and y is the logical channel number. See 

on page 48 for more information. 

IP Media Device

Represents a media resource that is used to control RTP streaming, monitoring Quality of 
Service (QoS) and the sending and receiving of DTMF digits. The format of the device name 
is ipmBxCy, where x is the logical board number and y is the logical channel number.
