IP Networking
IP Networking provides customers with a new option for networking systems together. Instead
of leasing dedicated voice circuits, customers can route voice traffic over the existing LAN/WAN
infrastructure.
IP Networking for the SX-200 ICP (MX, CXi, and AX) is supported. Controllers that are
geographically separated can be seamlessly networked to share information and services in a
transparent and cost efficient manner. IP Networking can be used as the primary communication
between controllers or as a backup to TDM networking. The IP Networking feature supports
both G.711 and G.729 encoding. Connections with up to 100 other network nodes and a total
of 24 channels are supported from any one node.
The following diagram illustrates a sample SX-200 ICP network.
The IP Networking call signaling supported is based on the Q.SIG feature set of the SX-200
ICP and consists of:
• Basic Call: incoming, outgoing
• Call Failures: Busy, Reorder, Alternative route
• Transfers: Supervised and Unsupervised with recall
• Forwarding: Always, Busy and No Answer
