Step 1: Configuring your SIP Trunk with 3CX

  1. Go to the 3CX Web client and follow the guide on how to configure a SIP trunk.
  2. Not compatible with Hosted by 3CX.
  3. Enter the main trunk number in the national format (e.g. 753675833).
  4. You can only present numbers associated with your account as Outbound Caller ID.

Step 2: TLS setup

CC Architect - SIP Connect trunks support SIP over TLS which can be enabled by following a few simple steps.

  1. Obtain the necessary root certificate needed for authentication. You can do so by contacting CC Architect Inc. support team: [email protected] .
  2. Navigate to your trunk settings and under the General section change the registrar port to 5063.

  1. Switch the Transport Protocol to TLS.
  2. A new field called “TLS Root Certificate” will appear. You will need to use it to upload the certificate acquired previously.
  3. Scroll to the top of the page and press OK. You should now see your CC Architect - SIP Connect trunk appear as registered.

If for any reason you need to revert back to UDP all you need to do is to reverse the steps and save the changes.
