Gigaset T440/T640 PRO settings.

For entering a new SIP trunk into the PBX, you need some steps:

Adding a new Gateway group
Adding a new SIP gateway
Defining the inbound routes (assignment of number to extension)
Defining the outbound routes

Let's assume our SIP trunk has following landline-numbers:

089/1234567 0-9

And we choose the last three digits also as extension for the user:

e.g. 678

Gateway Group

In the Gigaset PBX go to "Administration" - "Routes" - "Gateway groups" enter a name for the new group and click on: Create new group

In the Gateway group you have to define the Outbound Caller ID, the Asserted Identity settings, 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.

Example of Sipgate trunking gateway group settings.

Outbound caller ID

As we are using a block of numbers with this account, every user who is allowed to use this line will present the number 498912345 plus his extension to the provider.

The provider will then take care about the correct number-format to the callee. For example we will present e.g. 498912345678 to the provider and he will change it to 08912345678 to the callee.

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 Sipgate trunking accounts these settings need the same values than the Outbound caller ID.

Inbound DIDs

For incoming calls, you can use the regular expression, generated by the setup assistant. In your case you would have to adjust the city-code and the first part of the extension, 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. 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.

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 data you received from the provider.

Example of Sipgate trunking gateway settings 1/3.

Example of Sipgate trunking gateway settings 2/3.

Example of Sipgate trunking gateway settings 3/3.

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. 008987654321) 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' ! ! ! In case you want to use the prefix in the outbound routes, you have to enter '{prefix} to the dial command: SIP/{prefix}{number:1}@{gateway}

Group

Select here the previously created gateway group.

Update remote party ID (CLIP)

This setting is just optional, as the provider replaces outgoing CLIP which is not valid with the default number of the SIP account.

Advanced Parameter

You have to enter the complete term 'fromdomain=sipconnect.sipgate.de' , 'username=12345678t9' and also 'fromuser=12345678t9' 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.

Example of Sipgate trunking Inbound routes.

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.

Because we already receive the correct extension from the gateway group, we don't need any further number manipulation here.

In our example we forward incoming calls directly to the according extension.

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

Outbound routes

In the Gigaset PBX go to "Administration" - "Routes" - "Outbound routes" activate the Advanced options by clicking it to 'ON' and then pressing Show.

Example of Sipgate trunking Outbound routes.

Rule

Enter here a name for the according rule.

Date / Weekdays / Time

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

Pattern

In the pattern you define how the outside line is seized. In our example all dialled numbers starting with '0' will use the Gateway group Sipgate trunking.

Fax support

Fax currently (30.05.2015) has not been tested, yet. These results are without a guarantee. Due to different end-devices, configuration of PBX or other settings the fax transmission might fail.

We're currently working on an automatic fallback function, which should solve the remaining NOK constellations.
