Well oddly I've just managed to link into the Panasonic DBS38 remotely via it's RS232 port (amazingly the link has survived several PC changes!) and it looks as though it IS set up for DTMF - but there are loads of 'trunk line parameters' associated with it.
As I'm using 'remote desktop' over my internal network to access my Win7 office machine it's a bit flakey - I'll dig deeper when I can get the time actually t the host machine.
