Creating routes
Dialogic® Vision™ CX Video Gateway Administration Manual
Routing to a specific trunk group
Each route in the routing table that terminates to the PSTN can be assigned a trunk
group number to be used for the outgoing PSTN call. The gateway then chooses an
available circuit (based on the configured circuit selection algorithm) in the specified
trunk group to use for the resulting call.
If no circuits are available in the specified trunk group, then the outgoing call fails.
Failover routes can be configured with no trunk group specifier or with an alternate
trunk group specifier. If a route terminating to the PSTN does not have a trunk group
specifier, any outgoing or two-way trunk can be used.
To route calls to a specific trunk group, follow these steps:
Step
Action
1
Create route definitions in the Vision™ Console by associating trunks with route identifiers and
defining the circuit selection strategy for each trunk. For information, see
Trunks
on page 45.
2
In the gateway routing table, append the route number to the pattern in the To Outgoing field
using the following syntax:
;route:'
n
'
where the route expression is appended to the routing expression with a semicolon (;), and
n
is
a route identifier defined in the
telecom.conf
file.
For example, the following routing table entry routes all SIP calls to route 2:
ID
To incoming
From incoming
Mode
To outgoing
From outgoing
1
sip:(.*)@(.*)
sip:(.*)@(.*)
Route
tel:$1;route:'2'
tel:$1

Routing table expressions
