How Do I dial international calls in one click?

Hello Smart Guys,
I have been useing your services for long time and fully enjoying. I'm from US. I am making calls to India very often by useing different calling cards by type all the numbers one by one like call card number (1800 number) and Country code then phone number where i want to reach. Do you guys have any s/w that make all at once. (Ex: select number from contacts (should be set already) and dial like that.)

Thanks
Bala
