Configuring a Wavix SIP Trunk

Step 1: Sign-Up and Trunk Creation

  1. Sign up to the Wavix website. Wait for approval from Wavix before proceeding to the next steps.
  2. Navigate to “Numbers & Trunks” in the top menu and select “Buy” from the dropdown.
  3. Select the desired country and choose your number(s).
  4. Navigate to “Numbers and Trunks” and select “Trunks” from the menu.
  5. Click “Create New” on the top right.
  6. Select “Digest” to set a password for your trunk.
  7. Now choose a DID from the drop down box to act as the Caller ID or select “Passthrough” to set your Caller ID from 3CX.
  8. Click the “Create” button at the bottom of the page.

Step 2: Link trunks to DID

  1. Navigate to “Numbers & trunks” in the top menu.
  2. Select “My DIDs”.
  3. Select a number and from the three dot menu on the right select the “Edit DID”.
  4. Choose your SIP trunk from the drop down menu under “Destination”.
  5. Click “Add”.
  6. If you will be configuring SMS with 3CX, make sure the DIDs are SMS capable.
  7. Make a note of your credentials. You’ll need them to set up your trunk in 3CX.
  8. Click “Save” to apply changes.

Step 3: SMS-enable your numbers

  1. Go to “Numbers and Trunk” and select “My DIDs”.
  2. Click on the down arrow next to your number and select “Activate”.
  3. The activation can take up to 24 hours.
  4. This option is available ONLY for US & Canadian customers. Mobile numbers from other countries support inbound SMS by default. You will need to contact Wavix to enable the SMS.

Step 4: Set up outbound SMS

To create a Sender ID:

  1. Go to "SMS" in the top menu and select "Sender IDs" from the dropdown.
  2. Click “Create New” and select the Sender ID type, i.e. Alphanumeric or Numeric.
  3. Select the country you will send SMS to and press “Confirm”.
  4. Alphanumeric Sender IDs are not supported in the US and Canada. In many other countries, they require pre-registration by local regulators.
  5. Numeric Sender ID is a string of digits associated with one of the SMS-enabled numbers on your account. If you don't see any of your numbers in the Sender ID dropdown list, ensure that your Sender IDs have SMS capabilities.
  6. To use your DID as Sender ID, you need to activate the number for inbound SMS.
  7. In some countries, Sender ID registration may require additional paperwork. For details, hover on “i” next to the country name.

Step 5: 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. Enter the main trunk number in E164 format. For example if your number is (888)-233-5678, it should be entered as +18882335678
