Example of Easybell Trunk gateway group settings.

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 (international prefix)(country-code)(city-code)(number), you have to enter this number into the next line (here: 0049891234567$1, where the $1 represents the changing part).

For external calls, we will present e.g. 00498912345678 to the provider, and he we are using a standard SIP-account which has only one number assigned, every user which has the rights to use this line will present +498912345678 to the provider.The provider will take care about the number correct representation to the called party. He will present e.g. 08912345678 to the calling party.

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 Hosted PBXthe Easybell Trunk, you can use the entries from the outbound caller ID fields e.g. ^(.*\d\d(\d) and +498912345678For Deutsche Telefon Standard Hosted PBX SIP accounts this setting is just optional, as A-numbers won't be forwarded 0049891234567$1

Check also the correct settings in the Easybell web-portal to forward A-numbers in the correct format.

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). The During the call-setup won't remove the additional 0, but the Hosted platform will remove the leading 0 to call the remaining number will be automatically removed.

Gateways

This field will be empty when you create this Gateway group. It will show later the assigned SIP gateways.
