Hi Selintra,
Now you tell me

Anyhow I don't think that if I change the numbering back it will help now so I need to make the calls while watching the console. A couple of things that I have discovered is:
1). I had set the sibling trunk dial plan as _5XXX, so it was trying to dial the internal exts using the sibling

So I have deleted the route and the sibling trunk for the time being
2). I logged into server-manager and made my remote ext the closed and open inbound route for the SPA3k trunk and dialed it from my own phone and it rang in OK

My friend was in bed so I couldn't really do much more testing.
So when I have something to report from the console ooutput I will post it here, again thanks for your time and help.
Regards,
Del
