Example of HFO SIP trunk gateway group settings.

Outbound caller ID

As the last 3 digits of the trunk number blocks are matching the user extensions (e.g. 678), we just add the full extension to the trunk part 08912345.

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

Inbound DIDs

For incoming calls, we will route the complete number to the Inbound routes (e.g. 08912345621).

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). 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.

Dial command

The dial command is the command which is used in the asterisk software. The term {number:1}  means, that at the dialled number (e.g. 0089987654321) the first digit is removed. If you don't use a line access code (in most cases '0' is used), you have to remove the ':1' ! ! !

Group

Select here the previously created gateway group.

Update remote party ID (CLIP)

To display the correct extension at external parties, you have to use the P-Asserted-Identity (PAI) setting. If this is not selected, only the head-number (e.g. 0891234567-0) will be presented, no matter which extension is used to dial.

Advanced Parameter

You have to enter the complete term 'fromdomain=hfosip.de' in the value-field and press the plus-sign.

Underneath you will see then a preview of the entry in the sip.conf file.

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.

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

The shown example is the easiest way for blocks of numbers, but also other configurations or assignments are possible.

Pattern

In the pattern you define how the outside line is seized. In our example all dialled numbers starting with '0' will use the Gateay group HFO Telecom.
