VoIP Phone Systems
As the costs of telephone services continue to rise, companies are realising the cost-effectiveness and the quality of VoIP phone systems. With VoIP Phone system, you can easily implement an internal telephone directory and place free calls between any extensions worldwide.
Voice over IP or IP Telephony, also called Internet telephony, is the technology that makes it possible to have a telephone conversation over the Internet or a dedicated Internet Protocol (IP) network instead of dedicated voice transmission lines. This allows the elimination of circuit switching and the associated waste of bandwidth. Instead, packet switching is used, where IP packets with voice data are sent over the network only when data needs to be sent, i.e. when a caller is talking.
Its advantages over traditional telephony include:
- Lower costs per call, especially for long-distance calls.
- Lower infrastructure costs: once IP infrastructure is installed, no or little additional telephony infrastructure is needed.
- New advanced features.
Voice over IP traffic does not necessarily have to travel over the public Internet; it may also be deployed on private IP networks. The protocols used to carry the signal over the IP network are commonly referred to as Voice over IP or VoIP protocols.
The benefit of using this technology is the need for only one class of circuit connection and better use of the available bandwidth. IP telephony is commonly used to route traffic that may be originated from and terminated at conventional PSTN (Public Switched Telephone Network) telephones.
VoIP is now widely deployed by carriers, especially for international telephone calls. Users are typically completely unaware that their telephone call is being routed over IP infrastructure for most of its distance instead of the circuit switched PSTN.
VoIP is also used by large companies to eliminate call charges between their offices, by using their data network to carry inter-office calls. They may also use VoIP to reduce the costs of calls outside the company by carrying them to the nearest point on their network before handing them off to the PSTN.
With our VoIP Phone Systems developed by our partners, Presence, Fax & Voice Mail to email, Web conferencing and instant messaging are child’s play.
With the integrated 3CX clients, users automatically get access to advanced unified communications features – without needing to load or learn separate software – and that companies are normally charged extra for by other PBX vendors.
