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

Gateway Group

Per aggiungere un nuovo SIP Trunk nel PBX bisogna seguire questi step:

Aggiungereun nuovo Gruppo Gateway
Aggiungere un nuovo Gateway SIP
Definire le regole in entrata
Definire le regole in uscita

Gruppi Gateway

Nel centralino Gigaset vai in "Amministrazione" - "Route" - "Gruppi Gateway" e inserisci il nome del nuovo gruppo gateway e premi : In the Gigaset PBX go to "Administration" - "Routes" - "Gateway groups" enter a name for the new group and click on: Create new groupCrea nuovo gruppo

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 just the last digit of the trunk number block 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 +(country-code)(city-code)(number), you have to enter this number into the next line (here: +49891234567$1, where the $1 represents the changing part).

The provider will take care about the number representation to the called party. He will present e.g. 08912345678 to the calling party.

Info

title	Modifications

In case you are using not 3-digit extensions like 123, but 2- or 4-digits, you have to change the Search/replace pattern.

In our example we are using 3-digits, where only the last digit (inside the brackets) is taken into account.

For 2-digits it can look like this:

^(\d\d)

+4989123456$1

Now we're using the complete range from 10 to 99 as extensions, because \d\d is inside the bracket. Therefore we also have to remove the '7' from the 2nd line.

When extension 34 is dialing out, the resulting number would be +498912345634

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 Deutsche Telefon Standard Trunk, you can the entries from the outbound caller ID fields e.g. ^\d\d(\d) and +49891234567$1

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 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. 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.
