TCP-IP Communication port
The menu is used for management of ports through TCP/IP Communication port
which you can access your PBX. Basically, you can only or a port in this Add Remove
menu, enabling/disabling the authorisation requirement. It is only port 6992 that
requires authorisation after initialisation.
Figure: View of TCP/IP Communication port Menu Configuration
If the PBX is accessed through a password-protected port, the tag for direct Database
configuration is not displayed for the user or administrator by default. To display it,
assign the Read and Write rights to the user or administrator using the
Users – Users
menu, or use a PBX port without authentication. In such case, however, you Rights
expose your PBX to the risk of unauthorised access. The database access is
unnecessary for common configuration needs and should be granted to experienced
technicians only.
As shown in figure above, you can define more parameters for each port (except for
authorisation requirement).
HeartBeat packets – enable/disable sending of keep-alive packets on a port to
keep communication.
HeartBeat interval – define the time interval between the keep-alive packets.
