14.2 Repeated connection attempts with least cost routing
SwyxWare is able to repeat connection attempts over different trunks. For calls to external numbers, the connection attempts are repeated. The mechanism for repeats is as follows:
The trunk group that has the routing record with the highest priority for this call is determined in the first attempt, and from this group a trunk is selected which matches the caller's public number. If the routing record gives a specific call by call prefix, this is prefixed to the dialed number.
If no connection is established, the next routing record by priority is subsequently selected. Depending on the configuration, this can also be the same trunk group again.
Example:
 
Trunk Group
Priority
Number
Prefix
Repetitions

01033
0
4
TG3
300
+*
-
0
5
TG4

+*
-
0
In this example, an attempt is first made to dial a call via the trunk group TG2 (priority 600), and this is followed by three attempts (one + two repeats) to establish a connection via TG1 (priority 500) with the help of the LCR module. After this, one further connection attempt each (repeat = 0) is made with, in the order of priority, TG3 (with fixed prefix 01033), then TG4 and then TG5.
