Configuring the Trunk with 3CX

K2 Systems Portal

Before configuring your K2 Systems SIP Trunk in the 3CX Management Console, you must first log into the provider portal to get the credentials that you will need to register. Login with the credentials you have been given and go to “IP Centrex”“Phone Lines”.

Here you will see a list of all the numbers/DIDs that you have been assigned by K2 Systems.

Each number has its own unique set of credentials. This means that the procedure that will be described next will have to be repeated for every number you want to use in 3CX.

In the list of numbers make note of the ID value as this will be used as the Authentication ID, then press on the “Configure” button.

This will take you to this number/line settings. Here navigate to “My Profile”“Settings” and make a note of the “Service Password” value. This will be used as Authentication Password.

Note: Remember collect the credentials for each of the numbers you want to add to 3CX before continuing to the next section.

Adding the Trunk

Before reading this section, make sure you have followed the instructions and gathered in the information outlined in the previous section K2 Systems Portal and you have identified for each of your numbers which is the:

  • Authentication ID
  • Authentication Password

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

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

  • Select Country: CA
  • Select Provider in your Country: K2 Systems
  • Main trunk number: Enter the Authentication ID (e.g.18135910130)
  • Press OK

Under the “General” tab, in the “Authentication” section enter your Authentication Username and Password as collected in section K2 Systems Portal.

Once you have filled in these field, scroll to the top of the page and press OK. If you refresh the page you should see your K2 Systems Trunk appear as Registered.

Adding Additional Numbers/DIDs

When using K2 Systems SIP Trunks with 3CX, each of your numbers/DIDs must be added as a new SIP Trunk in the 3CX Management Console. This means that for every number/DIDs that you have been allocated by K2 Systems, you must repeat the instructions described in section Adding the Trunk using the corresponding Authentication ID and Password for each number (check section K2 Systems Portal for information how to acquire this information).

Creating Inbound Rules

Now that you have inserted all you DIDs/numbers into 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 K2 Systems SIP Trunks in 3CX, all numbers should be entered in an 11-digit dialing format (e.g. 18135910130), otherwise call routing may fail.

Outbound Caller ID

K2 Systems Trunks support Clip No Screening which means you can present any number you want when calling outbound. In order for this to work however, when configuring any field in 3CX that affects the Outbound Caller ID, the number you want to present as CLI must be entered in an 11-digit format (e.g. 18135910130).

Outbound Rules

When configuring your Outbound Rules make sure that all numbers are dialed either in the 10-digit or 11-digit format.

More information about how to create Outbound Rules and how they work can be found here.
