2.6.3. Terminal Trunk (PC#1, PC#2 only)
A SIP terminal trunk 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 terminal trunk 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 terminal trunk 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 to configure terminal trunks used by IP
PBX. Select Trunk -> Terminal Trunk and one can add, edit, and delete terminals. IP
PBX service must be reloaded to activate changes.
