SIP Trunk Pre-Requisites

Before adding any SIP trunks, the system must be configured to support SIP operation:

SIP Trunk Channel Licenses
The system can support 3 simultaneous SIP calls without needing licenses. Additional simultaneous calls, up to 20 in total, require the addition of licenses to the configuration.

VCM Channels
Note that for SIP calls the system also requires VCM channels. For a system those are provided by installing IP500 Combination base cards. Each of these cards (up to 2) provides 10 VCM channels.

STUN Settings
The system's STUN settings need to be configured to allow it to connect to the Internet for SIP calls. This is done through the STUN Settings for Network panel of the system's Advanced settings menu.
