VoIP stands for “Voice over Internet Protocol.” VoIP is simply the technology that convert your voice signals into a digital signal, first converting it to an analog signal, and then transmitting the sound over an IP network. To do this, the voice is sent through what is called an IP telephony system.
SIP Trunking is a set of technologies which are required to implement VoIP.
These include RTP (Real-time Transport Protocol), SIP packets, and Jitterbug. A VoIP system is made up of a gateway or network which has one or more IP phones on it. This makes VoIP phones available to businesses that might otherwise be unable to afford VoIP services or to use conventional phones.
There are two primary advantages of VoIP compared with traditional telecommunications systems. The first is that it allows multiple calls to occur at the same time, making it a cost-effective solution for businesses that make a great deal of long-distance calls. This type of VoIP call occurs without using any of the infrastructure which would normally be required such as a telephone exchange, public switched telephone network (PSTN), or cable lines. Instead, the voice-only calling process occurs between the VoIP phones themselves using what is known as an IP telephony system or ISSP. An ISSP will allow VoIP calls to be placed directly to the IP phones, which will handle the necessary transmissions for the calls to take place.
The second advantage is the ability to use VoIP for a variety of purposes beyond business communications. Many small businesses are now taking advantage of VoIP for voice and data applications. In addition to voice calls, they can also use VoIP for e-mailing and web conferencing among other applications. Many companies are now taking advantage of the ability to have resiliency in their communications systems through VoIP. Many small to medium-sized enterprises are already adopting VoIP for their disaster recovery needs and for applications and functions that do not necessarily require the use of a broader communications network.
One of the most common uses for VoIP for disaster recovery is through sip trunks.
An IP telephone network is combined with a private network that offers a dedicated gateway to the rest of the system. The gateway allows users of VoIP to connect to the rest of the system through what is called a sip trunk which allows them to continue to make local calls even though they are on a different network.
Since an IP telephone network can provide both voice and data services, the end users can continue to make local calls and use their credit cards to make international calls at the same time. The benefit of this is that they will only incur traffic charges for the actual amount of data used while making a local call. VoIP calls made from the local area network will not incur a charge for international calls and vice versa. This is one of the biggest benefits of using VoIP technology for voice and data applications over the public switched telephone network.
Many smaller businesses are finding that they need to replace their current phone systems or at least supplement their phone systems with a VoIP based system. Some of the reasons they are finding success with this is because the overhead associated with running a PBX business is very high. These businesses are also finding that with the help of voip phone service they can significantly reduce their capital costs associated with operating their business.
- The small business owner can also take advantage of the benefits of using VoIP phone service as well.
- Because these devices work so well for overseas customers and even for visitors to the United States the ability to make local calls is invaluable.
- There are many uses for a VoIP system for international calls and this is a great advantage to businesses in terms of communication.
- Because the VoIP protocol works so well there is no need to worry about outages or long-racing phone lines.
