3CX - IP Authentication Configuration

Overview

Skyetel is proud to be a certified and preferred provider for 3CX. This makes configuring Skyetel for your 3CX PBX very easy - simply select us from the drop down list and boom... you're done!

However, we know that many of our customers prefer to use IP Authentication instead of SIP Registration. This guide walks you through how to do that.

Please note, this guide is intended for the advanced 3CX administrator that is very familiar with configuring and troubleshooting their PBX and network.

Switching To IP Authentication 

There are 6 trunks required to use 3CX with IP Authentication. The first trunk is for Inbound Calling and the other 5 are for Outbound Calling. You can download all templates here:

If you want to add the High Cost Gateway, you can use the template at the bottom of this article.

Outbound Calling

Just like before, navigate to SIP Trunks, and then click "Import Provider." From this screen, upload all 5 Skyetel IP Auth (Outbound Calling XX).xml files to the PBX.

Once you have added the Outbound Calling profiles, navigate to "Outbound Rules" and click Add:

From here, add all 5 of the profiles to your outbound rules:

Adding all 5 of these rules insures that your PBX will failover to different Skyetel regions if one region experiences connectivity issues.

High Cost (International) Calling

Just like before, navigate to SIP Trunks, and then click "Import Provider." From this screen, upload Skyetel IP Auth - HighCost.xml files to the PBX.

You can download the template here: https://files.skyetel.com/3CX+IP+Authentication+HighCost.zip

Once you have added the Outbound High Cost Calling profile, navigate to "Outbound Rules" and click Add:
