Chapter 13 Voice Over IP (VoIP)
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
Enabled Dterm 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.
