  1. Adding a new Gateway group
  2. Adding a new SIP gateway
  3. Defining the inbound routes (assignment of number to extension)
  4. Defining the outbound routes

Let's assume our SIP trunk contains the following numbers:

0891234567[0-9]

And we choose follwowing internal numberblock:

67[0-9]

Gateway Group

In the Gigaset PBX go to "Administration" - "Routes" - "SIP gatewaysGateway groups" enter a name for the new line group and click on: Create new gatewayProvider settings:

Give the Line an unique name, insert the Registration user name and Password.

Number Area settings:

Just add the telephone numbers for this SIP trunk. The Country Code and Area Code can be filled in, if different than the default setting.

 

Miscellaneous

The provider-settings for Toplink Euroflat Ch2/4 are identical with the ones mentioned above.

group

In the Gateway group you have to define the Outbound Caller ID, the Inbound DIDs (how the number is forwarded to the Inbound routes) and the Inbound caller ID (number presentation of external caller). in addition you can permit here inbound calls in general for this gateway group.

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.

 

 

SIP gateway

In the Gigaset PBX go to "Administration" - "Routes" - "SIP gateways" enter a name for the new gateway and click on: Create new gateway

The SIP gateway contains all necessary data for the registration and dial command and how the number is delivered to/from the provider.

Just enter or choose the values according to your contract or NGN data you received from the provider.

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.

 

Inbound routes

In the Gigaset PBX go to "Administration" - "Routes" - "Inbound routes" select the correct Gateway group and press Show.

In addition it is advised to activate the advanced options by clicking it to 'ON' and then pressing Show.

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.

 In addition these two provider-profiles contain outbound-proxy settings to following IP-addresses: 213.218.22.30 (Ch2) or 213.218.22.20 (Ch4).
