Configuring the Trunk with 3CX

The general instructions outlining how to add a new SIP Trunk to your 3CX installation can be found here.

Adding the Trunk

Go to “SIP Trunks” and select “Add SIP Trunk”

  • Select Country: TR
  • Select Provider in your Country: Avencom
  • Main trunk number: This will have been provided to you by Avencom. You must enter the number in the international dialing format (e.g. 901234567890)
  • Press OK

Under the “General” tab, in the “Authentication” section you do not need to enter anything, these fields must remain empty.

In the “Registrar” field, you must enter the address of the SIP Server that your SIP Account has been allocated to. To acquire this information, you must contact your Avencom representative.

Once you have filled in these fields, scroll to the top of the page and press OK. If you refresh the page you should see your Avencom Trunk appear as Registered.

Adding Additional DIDs

To associate all other DIDs/Numbers you have in your Avencom account with 3CX, go to the Management Console → SIP Trunks, double-click on your Avencom Trunk and go to the “DIDs” tab.

Here you should already see 1 entry that is the Main Trunk number you have set. Add all other DIDs/Numbers you have to the list in a international dialing format (e.g. 901234567890) and press OK once you have finished.

Creating Inbound Rules

Now that you have associated all your DIDs/Numbers with your SIP Trunk in 3CX, you can create Inbound Rules to set where calls will be routed when those numbers are called. Instructions on how to create Inbound Rules can be found here.

Number Format

General

When configuring Avencom SIP Trunks in 3CX, all numbers should be entered in the International dialing format (e.g. 901234567890), otherwise call routing may fail.

Outbound Caller ID

Avencom Trunks does not support Clip No Screening which means you can only present numbers as Outbound Caller ID that are assigned to your trunk. These numbers must be presented in a international format (e.g. 901234567890).

Outbound Rules

When configuring your Outbound Rules make sure that all numbers are dialed  in the  International (e.g 901234567890) format. More information about how to create Outbound Rules and how they work can be found here.
