Thanks Gordon,
Forgot to say that with our desktop phones (Atcom AT-530) although
they normally transfer
calls using their built in FWD key, they will work using ## <number>
so the Trixbox bit seems to
work ok for them.

Looking through the trixbox logs, when using an AT-530 you see the
line
'DTMF received on channel SIP/blah' followed by the usual code as it
translates the specified
extension number and sets up the call. When you use the Siemens,
nothing.

I might add that it is not just one handset that has this problem. We
are running 20 or so desktop
phones and 12 Seimens handsets, using 4 base stations, and we have the
same problem with any
of the Siemens.

Thanks again for your suggestion,

Alastair.
