What are some advantages of VoIP?

Cost savings – the most attractive feature of VoIP is its cost-saving potential. VoIP reduces cost for equipment, lines, manpower, and maintenance. All of an organization’s voice and data traffic is integrated into one physical network, bypassing the need for separate PBX tie lines. Rich media service – VoIP technology makes rich media service possible, integrating with other protocols and applications. Rich media service not only provides multiple options of media to users but also creates new markets in the communications industry, such as VoIP service in mobile phones. Phone portability – VoIP provides number mobility: The phone device can use the same number virtually everywhere as long as it has proper IP connectivity. Many businesspeople today bring their IP phones or softphones when travelling, and use the same numbers everywhere. Service mobility – wherever the phone goes, the same services could be available, such as call features, voicemail access, call logs, security features, service policy, and so on. Integration and collaboration with other applications – VoIP protocols (such as Session Initiation Protocol [SIP], H.323) run on the application layer and are able to integrate or collaborate with other applications such as email, web browser, instant messenger, social-networking applications, and so on. Integration and collaboration create synergy and provide valuable services to users. Typical examples are voicemail delivery via email, click-to-call service on a website, voice call button on an email, presence information on a contact list, and so on. User control interface – most VoIP service providers supply a user control interface, typically a web GUI, to their customers so that they can change features, options, and services dynamically. For example, the users log in to the web GUI and change call forwarding number, speed dial, presence information (online, offline), black/white list, music-on-hold option, anonymous call block, and so on. No geographical boundary – the VoIP service area becomes virtualized without geographical limit. That is, the area code or country code is no longer bound to a specific location. Rich features – VoIP provides rich features like click-to-call on a web page, Find-Me-Follow-Me (FMFM), selective call forwarding, personalized ring tones (or ringback tone), simultaneous rings on multiple phones, selective area or country code, and so on.
