What is difference between VOIP phone and prepare calling cards ?

VOIP stands for VOICE OVER INTERNET PROTOCOL.


This is something like Voice chat that we do in YahooMessenger but the only other advantage is that we can make PSTN calls (calls to MOBILE PHONES AND FIXED LAND LINES).


This service is provided by some companies which have tieups with different Telephone operators and they forward your call to those companies and your call goes to the normal phone.


This is cheap and effective...but the other main disadvantage of this service is that YOU can not know exactly from which place the particular call is coming.(so emergercy call 911 service is not possible).


PrePaid Calling Cards are those where you buy some talking min before u dial a phone..so as you talk on your phone the money from ur card (phone) gets diducted and finally u will not be able to call anymore.


Thanks

VOIP is a type of phone service, while calling cards just bill you for long distance while you use another company's phone service.
