SIP Trunking and Hunt Groups on the SPA8000
The SPA8000 supports SIP Trunking, which allows you to connect a traditional PBX to VoIP
services. In this configuration, calls go through the ITSP rather than the PSTN, yet the call
routing functionality is similar to that of traditional PSTN lines.
You can configure up to four trunk groups for the purpose of inbound call routing and
outbound caller identification. You can configure a trunk number on the SPA8000, such that an
incoming call automatically rings the grouped lines simultaneously or in a specified order. For
outbound calls, SIP Trunking ensures that all calls on a trunk line can be identified by the trunk
number and a common caller ID. This feature helps you to ensure that calls are directed to
available lines and that work groups such as sales teams can work together to answer calls. In
addition, teams can project a common identity when placing outbound calls on a trunk.
This section provides information about SIP trunking and explains how to configure your trunk
groups.
