Capacities of All-Trunk Systems
Table 43 summarizes system trunk capacity in terms of the number of trunks provided in possi-
ble all-trunk systems. A typical installation may include a combination of hard-wire trunks and
IP gateway trunks.
IP and SIP Endpoints
The Inter-Tel 5000 platform supports Inter-Tel IP phones, IP and SIP trunk gateways, and IP
Single-Line Adapters (IP SLAs).
Multi-protocol endpoints
A multi-protocol endpoint is one that operates either in Inter-Tel Protocol (ITP) mode or in
Session Initiation Protocol (SIP) mode. A SIP server is required for SIP mode operation.
Multi-protocol endpoints include Models 8622, 8662, and 8690. Multi-protocol endpoints
operating in ITP mode require Category A licenses. Multi-protocol endpoints operating in SIP
mode require Category C licenses.
IP and SIP Trunk Gateways
Trunk gateways provide the signal conversion necessary for VoIP conversations to be carried
across the public telephone network.
IP Single-Line Adapters
One IP Single-Line Adapter (IP SLA) provides the interface between a single local area net-
work (LAN) port and one single line endpoint. Each IP SLA requires a Category C license.
