You will also be presented with some new options which will help you configure you SIP Trunk Call Manager Service. These options are:
|
Announcement |
Announcements can be combined with an underlying call plan to play a message to the caller prior to the call connecting, or alternatively as a broadcast which plays an announcement, such as notifying the caller of a change of numbers, and then ends the call. |
|
Area Based Routing |
Area nodes are used to define an underlying call routing planning based on the originating telephone number, for a predefined area name consisting of one or more area codes or CLIs. |
|
Standard Auto Attendant (IVR) |
The Interactive Voice Response (IVR) control feature enables the creation of a personalised menu announcement with up to 10 options to be played to the caller, each leading to a defined call routing / action based on the caller’s key press on their keypad. |
|
Call Divert Barring |
This allows you to bar diverts to certain destinations. These are: International Low Risk Destinations International Medium Risk Destinations International High Risk Destination Special Service Numbers (084) Mobile Destinations 01, 02, 03, 05 and 080 destinations For more information on International Destination Risks please see the Billing Home page on the Gamma Portal (Billing Billing Home) |

Number selection #
Now you can add Gamma ranged telephone numbers to your new SIP Trunk. Select up to 5 prefixes and the quantity of numbers required for each. Ticking consecutive will ensure you are provided with a consecutive range.
- You must check the availability of the range before proceeding with the order.
- The CLI rules will set the format of the CLI and DDI presented for incoming calls.
If you require a specific number, you should use the Gamma Number Search under Help and Support to identify what numbers Gamma has available and then use the web
chat facility to get the number allocated to your account.
If there are any unavailable area codes for your selection you’ll be presented with a message that advises there aren’t enough available. To progress the order you should select any available number (which can be used for testing) and when your order is complete then you can contact Number Management who can review number availability.
If you are wishing to port your number(s) to Gamma, then you still need to select one number from an area so that we can set the Endpoint up. Your endpoint also needs to be set up before you place your Geographic Port Order. For more information on porting please see our Gamma Numbers and Porting guide.
- The default format for both CLI and DDIs represented for incoming calls for Direct Routing for Microsoft Teams is E.164 format (i.e. +441618703374).
You can change this to the following:
- Leading zero (i.e. 01618703374)
- No leading zero (i.e. 1618703374)
Customers should be aware that modifications to the format of the B-number presented to the customer must align with the format currently defined in the
applicable Microsoft calling plan in the customer tenant. If the two formats are not aligned, then calls will fail.

The verification process requires the customer Microsoft 365 administrator to generate a set of DNS (TXT name and value) records in their tenant, one set for each domain. You should then contact Gamma support desk to Update DNS Records before you can continue the manual configuration.
