3CX SMS setup guide
This document explains how you can configure your 3CX in order to send and receive SMS and MMS messages with Wavix
Register a Sender ID

Before sending an SMS or MMS message, you need to activate a Sender ID on the Wavix platform. A Sender ID is the message sender details recipients will see on their devices. Sender IDs can be either numeric or alphanumeric presenting your brand or service name.

Important

You must use Numeric Sender IDs, if you want to enable 2-way messaging service. For one-way SMS you can use both Numeric and Alphanumeric Sender IDs.

The below steps are only mandatory if you’re planning to send messages using a U.S. or Canadian phone number as Sender ID. In case you will be using a mobile number from other countries or an alphanumeric Sender ID, please scroll down to the Create a Sender ID on the Wavix platform section.
