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: BE
  • Select Provider in your Country: TeleVoIP
  • Main trunk number: This will have been provided to you by TeleVoIP. You must enter the number in the international format (e.g. 3212345678)
  • Press OK

Under the “General” tab in the “Authentication” section, enter your Authentication ID and Password (these will be supplied to you by TeleVoIP).

Adding Additional DIDs

To associate all other DIDs/Numbers you have in your TeleVoIP account with 3CX, go to the Management Console → SIP Trunks, double-click on your  TeleVoIP 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 the International number format (e.g. 3212345678) and press OK.

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 TeleVoIP SIP Trunks in 3CX, all numbers should be entered in the International number format (e.g. 3212345678), otherwise call routing will fail.

Outbound Caller ID

TeleVoIP Trunks support Clip No Screening which means you can present any number as Outbound Caller ID when performing outbound calls.

Outbound Rules

When configuring your Outbound Rules, numbers can be dialed in all valid number formats (National or International). More information about how to create Outbound Rules and how they work can be found here.
