– Name — an arbitrary name for identification,
convenient for the operator;
– Load balance mode — type of load balancing
between SIP servers:
– Active-active — the load is balanced
between SIP servers in a 50/50 ratio;
– Active-backup — all load is transmitted
via the first SIP server. If the first SIP
server is unavailable, the load will be directed to the second SIP server;
– Load balance timeout, sec — the time after which the call will be routed to a backup SIP server if the server
to which the call has already been routed is unavailable;
In the section SIP Destinations, destinations to
be added to the trunk are selected. It is also possible to
delete a destination from the trunk by clicking the icon
("Delete") in the selected row. The green arrows
below the list allow moving the highlighted entries in
the table, adjusting the order (priority) of the
destinations created.
4.1.3.5 Rule set
In this section, the rules for switching calls via SBC are configured. Up to 512 rule sets can be created in total,
in which up to 1000 rules can be distributed. The limit on the number of rules is common to the whole SBC, one set
of rules can contain up to 1000 rules. Thus, for example, one rule set with 1000 rules or 512 rule sets with two rules
in each can be created on SBC.
To create, edit or remove interfaces, use 'Objects' — 'Add an object', 'Objects' — 'Edit an object' and 'Objects'
— 'Remove an object' and the following buttons:
– «Add»;
– «Edit»;
– "Delete".
