Voice over IP Technology (VoIP)
Voice over IP Technology (VoIP)
W e have been successful in delivering voice over IP technology (VoIP) to our clients. Our engineers are certified to successful implement the VoIP solutions according to client's needs. We focus on client's benefit why they should replace legacy phone by selecting the VoIP instead especially, the cost savings that can be up to 60% so that's why we cannot refuse the VoIP technology.
VoIP Benefits +
Cost savings: The most attractive feature of VoIP is its cost-saving potential. When we move away from public switched telephone networks, long-distance phone calls become inexpensive. Instead of being processed across conventional commercial telecommunications line configurations, voice traffic travels on the Internet or over private data network lines.
Rich media service: The legacy phone system mainly provides voice and fax service even though limited video service is possible. However, the demand of users is much higher than that, as shown in today's rich media communications through the Internet. People check out friends' presence (such as online, offline, busy), send instant messages, make voice or video calls, transfer images, and so on. 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: The legacy phone system assigns a phone number with a dedicated line, so you generally cannot move your home phone to another place if you want to use the same phone number. It is a common hassle to call the phone company and ask for a phone number update when moving to a new house. However, 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 traveling, and use the same numbers everywhere.
Service mobility: The context of mobility here includes service mobility as well. 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. The integration and collaboration create synergy and provide valuable services to the 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 provide 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. For example, you could live in South Korea but subscribe to a U.S. phone number, which makes it possible that all calls to the U.S. become domestic calls (cheaper) even though you live in South Korea.
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. Now that you are aware of many of the benefits, the next section takes a look at several disadvantages.
