[plug] Dial back

[Quintin Lette]

Unfortunately this is way  beyond the scope of Linux for dummies... :-)

After a search on Google for Call Back it seems there is a lot of information 
out there, but you need to try and login with a script to initiate the call.. 

As for the actual dial out bit, first of all you need the client system to act 
as a dial in server (this is just so that the windows client wants to pick up 
the phone when it rings and answers all of the negotiation correctly) Dialin 
script wise it should be almost identical to an ordinary you dial out sort of 
connection.. so the issue here is more the windows client knowing how to 
answer the call (its available from Windows 95 onwards out of the box, maybe 
even earlier) just remember to set autodns to 0 on server.  On the client 
side you want to set your default route and dns manually to use the dialin 
connection as the default behaviour is the opposite.

Unfortunately I no longer have access to 2 phonelines so I am unable to test 
and give you a working script :-( but search google and the likes.. or maybe 
someone else can answer you better :-)

Regards

Quintin
