VoIP which is also known as Voice over Internet Protocol is a combination of hardware and software that enables the delivery of voice and other multimedia over Internet Protocol (IP) networks, instead of the traditional Public Switched Telephone Network (PSTN), which is the conventional analog phone system. It is also commonly known as Internet Telephony. A-Z SIP termination is the service that allows VoIP technology to be used for making calls to phone network across the globe. VoIP is also available on several smartphones, personal computers and other devices that can access the internet. 3G/4G or Wi-Fi can be used to make calls and send text or multimedia messages.

These days it has become common for telecommunications providers to use VoIP termination technology to connect switching centers and to interconnect with other telephony network providers. The call may need to be routed through various telephone service providers before it reaches the intended telephone company and is received by the recipient. This process in referred to as VoIP call termination or voice termination.

There are several advantages of using VoIP but the three biggest advantages are:
1. Cost Saving – Globex Telecom VoIP services are most popular for being affordable. Calls to the same VoIP providers are free and rates for calling landlines and mobile phones around the world and very low compared to the conventional options.
2. Portability – All you need is an internet connection and you can use your VoIP device to make calls using the IP.
3. Flexibility – VoIP offers a very feature-rich experience, such as: call hold, call transfer, call hunt, conference calling, and auto-attendant phone menus. Additionally, you can use Virtual faxing or IP faxing as well. You can simply use the email account you already have with a hosted VoIP system and send and receive faxes.
There are several VoIP providers in the market and they offer various cheap VoIP services.

Some of the more popular providers are:
1. Skype
2. Lingo
3. RingCentral
4. Vonage

One of the most popular features, for call center agents, offered by VoIP providers is Predictive Dialer. It is an automated telephone dialing system that radically increases the number of live calls for the call center agents. Without the use of a predictive dialer a significant amount of time of call center agents is wasted on unanswered calls, disconnected calls, busy lines, answering machines and various automated services. However, the VoIP predictive dialer connects the agents only to the calls that are answered by people, saving precious time and resources.

Another niche in the VoIP industry is the wholesale SIP termination. Typically, the demand is generated by Service Providers working to gain a competitive edge over the other players in the market by minimizing their cost. If a service provider is looking forward to delivering VoIP to a broad customer base then an effective strategy to achieve it would be becoming a wholesale VoIP reseller. And lately, VoIP reselling has become a popular model, and if done right it has the potential to become a very lucrative business.
