Comparison of VoIP software 4617475 223752467 2008-07-05T16:48:50Z 149.224.140.141 {{listdev}} [[Voice over IP]] (VoIP) software is used to conduct [[telephone]]-like voice conversations across [[Internet Protocol|IP]] based networks. For residential markets, VOIP phone service is often cheaper than traditional [[PSTN]] phone service and can remove geographic restrictions to telephone numbers (i.e. have a "New York" PSTN phone number in Tokyo). For enterprise or business markets, VoIP enables the enterprise to manage a single network (the IP network) instead of separate voice and data networks, while enabling advanced and flexible capabilities to the end user. == General softphone clients == <!-- ######### EDITORS TAKE NOTICE ########## In the "License and source" column, please restrict yourselves to: * [[Free software]] * [[Proprietary software|Proprietary]] [[freeware]] * [[Closed source|Closed]] * [[Open source|Open]] (just in case) Should the application be dual licensed, indicate so by separating them with a slash.
