What is VOIP? VoIP or Voice Over Internet Protocol, is the transmission of voice traffic over IP-based networks. Since its birth, it quickly became popular because of the amount of money an individual can save when it is used for long distance calls. VoIP services are cheap, compared to traditional phones, and there are even software available to make free international calls. Unfortunately, these kinds of software only works for PC-to-PC calls. To take full advantage of VoIP, a VoIP phone is recommended. Like all other traditional phones, VoIP phones are packed with regular and advanced features including call waiting, call barring, call conferencing, fax, and many more. Its ease of use, features, and affordability made VoIP the new face of communications today. Why Choose OpenTone? OpenTone Communications is one of the leading VoIP Providers in the Philippines.
