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: NL
  • Select Provider in your Country: Signet
  • Main trunk number: This will have been provided to you by Signet. You must enter the number in the national number format without the leading 0 (e.g. 852733645)
  • Press OK

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

Once you have filled in these fields as given to you by Signet, scroll to the top of the page and press OK. At this point if you refresh the page you should see your Signet Trunk appear as Registered.

Adding Additional DIDs

To associate all other DIDs/Numbers you have in your  Signet account with 3CX, go to the Management Console → SIP Trunks, double-click on your  Signet 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 national number format without the leading 0 (e.g. 852733645) 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 Signet SIP Trunks in 3CX, all numbers should be entered in a national number format without the leading 0 (e.g. 852733645), otherwise call routing may fail.

Outbound Caller ID

Signet SIP Trunks support Clip No Screening which means you can present any number you want when calling outbound.

In order for this to work, the numbers must be presented in a national number format without the leading 0 (e.g. 852733645).

Outbound Rules

When configuring your Outbound Rules make sure that all numbers are dialed either in the National (e.g. 0852733645) or  International (e.g. 0031852733645) format. More information about how to create Outbound Rules and how they work can be found here.
