Example of HFO SIP trunk gateway group settings.

Outbound caller ID

As just the last 3 digits digit of the trunk number blocks are matching the user extensions (e.g. 678), we just add the full extension to the trunk part 08912345block is changing, you can select just the last digit (in brackets) and put it into the variable $1. As the provider wants the signalling number in the format (city-code)(number), you have to enter this number into the next line (here: 0891234567$1, where the $1 represents the changing part).

For external calls, we will present e.g. 08912345678 to the calling party.

Asserted Identity

These fields are used specially for external forwardings. Some providers need special settings in order to present the correct number at the receiving party. For HFO Telekom, you can forward the number as it is with ^(.*) and $1

Inbound DIDs

For incoming calls, we will route the complete number to the Inbound routes (e.g. 08912345621)you can use the regular expression, generated by the setup assistant. In your case you would have to adjust the city-code and the pilot-number, according to your line-settings.

^(?:(?:(?:0049|\+49|49|0)?89)?12345)?(.*)

This expression cuts all possibly available country- and city-codes and the pilot-number from the incoming number and only the extension is remaining (here: 678). This will be forwarded to the Inbound Routes.

Inbound caller ID

For incoming calls, we will add an additional 0 in front of the external number of the caller, in order to use the callback-feature of the phone (e.g. 008912345678 0089987654321). During the call-setup the additional 0 will be automatically removed.

Gateways

This field will be empty when you create this Gateway group. It will show later the assigned SIP gateways.

Rule

Enter here a name for the according rule.

Date / Weekdays / Time

With these settings you can configure a time-controlled routing to different targets.

Pattern / Target

In the pattern you define which part of the incoming number is used to forward the call to the according extension.

In our example we cut off the first part 08912345 and forward all additional numbers (e.g.678) to the target.receive alread the correct extension from the gateway group. Therefore no further number-manipulation is necessary.

When the PBX finds an according extension it will route the call to it.

But you can add here exceptions from this rule, for example for internal fax users or waiting queues, etc.

Please have in mind the order of these rules, as the system is using First Match!!!The shown example is the easiest way for blocks of numbers, but also other configurations or assignments are possible.
