For anyone else trying to do this, I've finally achieved it :)

It turns out not even to need to !dnid option...

Set(CALLERID(num)=${SIPuser})
Dial(SIP/${SIPdial}:${SIPpass}::${SIPuser}@${SIPhost})

The CallerID setting is necessary otherwise Asterisk will send the 
authentication request, but the Dial request will get rejected with a 403 
Forbidden, because the username will be the inbound Caller ID from the 
original call.

I hope this helps others avoid spending as much time as I have trying to work 
this out.  Anyone in charge of Asterisk documentation is very welcome indeed 
to quote this as an example on pages such as 
https://wiki.asterisk.org/wiki/display/AST/Asterisk+13+Application_Dial


Best regards,


Antony.
