Voice over Internet protocol (or VoIP) is a term used for a number of protocols that are used to carry voice data over packet switched networks. Beforehand, telephony used a dedicated line, that was only for calls. This was known as PSTN (or "public switched telephony network"). Using VOIP will reduce costs, as the "dedicated line" for telephony (and fax) is no longer needed. know more: [[Call Termination Sell>http://www.voipbiznessforum.com/Forum-Call-Termination-Sell]]
