Make sure you inform Telstra it is a On Ramp Home and it is being connected 
by person whom has a name on current bill at residence?? Not a business name.

All phone lines in residence will be reduced to two lines one data always(DoV)
when switching in dual channel (128k) you will lose all house phone 
connections to data. Unless Telstra  allow a third line without losing on 
Ramp Home, not sure about this one, let us know outcome though I would love a 
third line, bastards said no.

connections?

Find an old, but farely powerful retired machine and put IPcop 1.3 with 
netjet pci card works a treat 10 min install has lots of extras, besides 
being a firewall/gateway. Has option of settiing a vpn if security is an 
issue? Will do trick, with a little thought.

The router at the other end has to have DoV capabilities for it to work which 
means a ISDN connection at office. ISP solution not looking so bad? But I am 
not sure how traffic works as modem at office end would assume it is a non 
data call, but all business ISDN is charged?

Check with Arachnet and Westnet as they supply DoV. 

Another solution, just a guess as I do not know what web/mail services are 
being supplied, but what about hosting as basic name hosting packages work 
out around the 150-200 a year mark with about 1 gig of traffic or more.

Microwave, cost could be problem plus both need to be line of sight?
