thanks a lot for the prompt reply
so do you mean that the 'dial in and back out' thing and the '3 way call' thing can not be done at the same time? does that mean that no matter what happen one of the caller will get a busy line? am i right?
basically its not really a personal thing.i will be having a small business center in our local area..just for small close knit community and with it i plan to include voip innternational calls.(it will greatly hellp all of us having a cheap calls specially that christmas is coming).
though as you can see im so new at this things thats why i thought of starting with simple devices like phonegnome or spa3000 but as you said it will not accomplish my obejective of having at least 2-3 simultaneous calls.
dont you guys have some kind of a package plan for individuals like me ? just rely on your technology and know how? i hope.
