Gigaset T440/T640 PRO settings.

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

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:

0441234567[0-9]

...

...

...

...

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 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: 0441234567$1, where the $1 represents the changing part).

For external calls, we will present e.g. 04412345678 to the provider, and he will take care about the correct representation to the called party.

Asserted Identity

These fields are used specially for external forwardings. For Aarenet VoIP Trunk, you can use the same settings as for 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 pilot-number, according to your line-settings.

 ^(?:(?:(?:0041|\+41|41|0)?44)?12345)?(.*)

...

Inbound caller ID

For incoming calls, we will forward the external number of the caller "as-is" to the phone (e.g. 044987654321). This number can then be used from the call-lists for re-dialling.

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 VoIP trunk data you received from the provider.

Registrar

Use here the SIP-Server / Registrar (received by Aarenet). In this case an IP-address is used.

Proxy

The tests were performed with the the same IP-address as used in the Registrar field, followed by ';lr' , which means "loose-routing".

User

Enter here the Username (Benutzername) you have received by Aarenet.

Password

Enter here the Password (Passwort) you have received by Aarenet.

Dial command

The dial command is the command which is used in the asterisk software. The term {number}  means, that the number (e.g. 04455007000) is dialled as entered. If you use a line access code (in most cases '0' is used), you have to add ':1' after "number".

Group

Select here the previously created gateway group.

Update remote party ID or P-Asserted-Identitiy (CLIP)

These settings can be left on the default setting (no - Deactivated)

From Domain

Enter here the Domain/Realm delivered by Aarenet. You can use the same value as used for the Registrar.

T38 support

In order to have a better fax-support for fax-machines, connected to the FXS ports please deactivate this option.

All tested scenarios were ok with this parameter deactivated.

...

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 receive already 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.

...

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.

Fax support

Following table shows you the current state (09.03.2017) of supported fax constellations. These results are without a guarantee. Due to different end-devices, configuration of PBX or other settings the fax transmission might fail. More info about fax via VoIP networks can be found here.
