I am using the exact same details as before (See below), and it looks like the trunk is registering, however no calls in or out.
If I try and dial out I get the "All circuits are busy now" congestion mesasge. If I try and dial in, I get the iTalk VM system.
If anyone can point me in the right direction I would be very grateful.
Trunk Name: iTalk Napier

Register String: 646843XXXX:<MY PW HERE>@npe.italk.co.nz/646843XXXX
