At the office:

The PABX is a GDK16.

The SPA3000 is hanging off an analogue extension of the GDK16.

On an incoming PSTN call, firstly Ext 102 (my office) rings for 10
seconds, then if no answer Ext 106 rings (the SPA), then if no answer
finally hunts to Ext 104 (the shop itself). Thats why I had hoped to
leave the SPA on-hook unless or until I picked up my IP Phone at home.

The SPA3000 connects into a Draytek router with all conceivable ports
routed through to it.

At home:

Simply a Grandstream BT-101. Again all ports routed to it ok.


Jono, unless its obvious to you from the above, thanks but please
don't worry - I am able to remotely enable the PSTN to VOIP gateway of
the SPA from home when I'm working at home, and turn it off again
remotely when I've had enough for the day! I suspect an SPA3000 at
each end would be far more compatible and the best solution. And I
don't wanna take up too much bandwidth of this group.

Cheers, Chris
