The 3cx academy recommends using a trial licence in order to complete the process.

But then you try to add a SIP trunk and receive the alert "Only one trunk allowed for trial accounts"

Could you please advise how to get around this issue?
 
That…sounds like you’re adding two?

I've created a Twilio trial account, with an AU phone number.

Hello,


I am 99% confident (because it happened to me too :) ) that the error you are getting is from Twillio, since their system for trials allows only 1 trunk, and our automated Twillio template is set to create a new trunk with them via API - simplest solution, delete the trunk you created on Twilio and run through the 3CX wizard again - any DID you had can be attached to the new trunk.
