The "Routing" Tab
Specify on this tab the forwarding criteria to be used in relation to the number or URI.
Use
Activate "Use this Trunk Group for Calls to the following" if you want to forward calls over these trunks which meet the following conditions.
Give the public numbers or URI that should go over this trunk. You can use placeholders here (Placeholder).
In the field "With additional Prefix", you have several options:
NoneIn this case, no further prefix (Call-by-Call provider selection) is added to the destination number.
<Number>Enter directly into the field a numerical sequence, which is then prefixed to every destination number that is routed via this trunk group, e.g. "01013".
Specify how often a connection attempt should be repeated (standard: 0). If LCR is not used, but instead the call by call prefix of an economical but heavily overloaded provider is dialed directly, these repeats can be useful in order to try this least expensive provider a number of times.
Activate "Do not use this Trunk Group for Calls to the following" if you don't want to send calls with certain destinations via this trunk group.
For each routing record, you can allow or deny only one type of condition.
Example of the use of placeholders:
If you want to allow only external numbers for a trunk group, then you must enter the following:
Under "Use this Trunk Group for Calls to the following", in the field "Destination number or URI", enter "+*". All calls going to an external number (canonical format, e.g. +4420 5666777) are then allowed Under "Do not use this Trunk Group for Calls to the following", in the field "Destination number or URI", enter "*". All calls that are not explicitly allowed above are then disallowed. As a result of this setting, calls intended for internal subscribers (not in canonical format) are not routed via this trunk group.Record Priority
Specify the priority with which this forwarding is applied to a call. You can decide a priority between 0 (low) and 1000 (high).
