Chapter 13 Voice Over IP (VoIP)
There are two types of connections available for CCIS Networking via IP:
CCIS Networking via IP (Peer-to-Peer Connections Basis)
When the distant systems are 2000 IPS, the systems are connected on a peer-to-peer basis. The CCIS
call control signals are transmitted between the built-in IP trunks (CCIS Handler; CCH) on the MP card,
over the Local Area Networks and Wide Area Networks (LAN and WAN). For connections between IP
term
Enabled D terminals, voice signals are also transmitted over the LAN and WAN. For connections
between legacy terminals, voice signals are transmitted via IP-PADs. This connection is also available
when the distant systems are 2400 IPX that supports peer-to-peer connections.
Example IP Enabled Terminals Peer-to-Peer Connection
Example IP between Legacy Termainls via Peer-to-Peer Connection
