4.8 Terminal Trunk Configuration
A SIP trunk terminal refers to a SIP account for a remote SIP trunk to register with.
It terminates SIP registration and invitation from a remote IP PBX and relay calls to
local clients, PSTN trunks, or further SIP trunks. In a site-to-site SIP trunking
application, a SIP trunk on one side usually pairs with a trunk terminal on the other
side to form a unidirectional call hand-off path. To allow trunking in the other
direction, the two sides swap roles and form another pair. Since a trunk terminal is
the account for a SIP trunk to authenticate with, exact the same identifier and
password must be used for both.
The TERMINAL TRUNK MANAGEMENT page allows the administrator to
configure trunk terminals used by TAINET IPBX 230. Select Trunk -> Terminal
Trunk, and one can add, edit and delete terminals. Go to Service -> IP PBX
Service, and click RELOAD to activate changes.
