To answer my own question about this 220v which I'm trying to get to talk to bulldog

It seems a good way to change things is to export the settings, tidy
them up and re-import them, they look like this first off

Now that answers the 'how do I set someone elses voip up, but,
interestingly it WON'T allow you to change the ipext ,demand, and auth
settings under ppp_conld1.... bugger - I wanted to set it to chap.

also encap is set to LLC. what format does this want for vc-mux? VCMUX
or VC-MUX or what?

the old javascript trick seems to start the logon procedure, but it
fails to connect..... 8-(

any ideas anyone? I'm just after a cheap source of VoIP routers without
having to go the Draytek 2800v route.

also, is the 220v modelled around any other router who firmware might
work, rather like the safecom conexant chipset routers. This box uses
the new broadcom BCM6348KPB chipset!
