Guide on setting OnSIP trunking

Hi dear members,

I am trying to set sip trunking with

First, I created a dev account following the link in
Logged in and created users on, and enabled one user to support onsip trunking.
After obtaining info about “OnSIP Trunking User”, followed the step-1 of the guide to setup on Asterisk, but running “sip show registry” shows empty rows.

How can I setup this trunking using FreePBX interface, or should I change the “*custom.conf” files manually?
Any guide is appreciated.
