QuickDial is an auto-dialer extension for Firefox which allows you to initiate a phone call to the selected telephone number.
The user must sign-up with at least one of the providers listed for QuickDial to be of any use. The providers are alternative long-distance providers, dial-around providers, VOIP providers, etc. Basically, any type of provider can be listed in QuickDial.
When the user initiates a call, the user's preselected telephone (home phone, cellular telephone, etc) will called by the selected provider and once answered, the call will be connected to the selected telephone number.
Users can subscribe with multiple providers to benefit from the best rates for the specific destinations being called. (Future versions of QuickDial will automatically suggest the least expensive provider).
