I am trying to set up a SIP Trunk with the Twilio (Auto-setup) option and getting an error on the step where the trunk name is entered. I get a generic 500 with no additional information. The docs seem to imply that there is a way to set up the trunk manually as well. I did set it up manually in Twilio, but I don't know how it can be added to 3CX. I have no option in the dropdown for a manual entry and I am forced to choose a VoIP provider. Has anyone else encountered this error?

Error during Twilio (Auto-setup):

Available options after clicking "Add trunk":

If memory serves the trunk name has to be unique…?

That was the problem. I had tried several different variations, like "default", "testtrunk", etc, but apparently they were all too generic. Thank you!
