SOLVED Using TelecomsXchange with 3CX?

[sortons]

Hi,
I've been using TelecomsXchange trunks on IncrediblePBX for the last year without any problems - that install is based on http://nerdvittles.com/?p=24702.

Now the question is how to make it work on 3CX... I got to the point where the format 3CX sends out is similar to Incredible PBX, but here's the error I'm getting:

Any suggestions?

So, I had to figure this one out... It works as expected with the following observations:
- create one trunk / seller
- the seller's Tech Prefix needs to be prepended to the respective route on the Outbound Route
- add a few routes (trunks) for different sellers for the same outbound route

Last time I looked at this, I only had one seller in the outbound route and that seller was unavailable when I ran the tests. That simple!
