DG-104s MGCP help needed

Ive tried to sort this out myself but feel its time to ask for help so I can move on. I'm not too far from the base of that steep learning curve, so I apolagise if I miss any important details.

I have Trixbox 2 rc1 and am struggling to connect a Dlink DG-104S to it. Its a MGCP device, from old posts on the net, it seems people had it running with various Asterisk setups.

I have no dial tone on the phone connected to it and it will not make or recieve a call. Although if I dial its extension number from a softphone it seems to ring on the softphone end for a split second before going to service unavailable.

The Telnet window connected to the device shows messages like this;

000066276 mgcpimh: invalid endpoint aaln/1@DG-104S
000066276 xgcpimh: CA message rejected
000066276 XGCP PARSE: illegal endpoint

it shows this any time I take any action, phone off hook, on hook, attempt to dial it.

asterisk cvvvvvr gives me this when I pick up the phone and dial 100 which is the extension number of a soft phone;

Connected to Asterisk 1.2.13 svn rev 47264 currently running on asterisk1 (pid = 2419)
Verbosity is at least 5
