Let’s start it “What is VOIP” in layman ?

What is VOIP?

VOIP is an abbreviation for Voice Over Internet Protocol. As the name refers “VOIP is a technology that has revolutionized the way a call center makes the call. VOIP utilizes the method of the internet to transmit voice calls instead of traditional phone calls.”

Typically call center uses multiple telephone lines to connect with the customer. The higher number of customers means more phone lines, hardware, manpower, and a dedicated IT department.

With VOIP in place, you can get rid of all this setup. Just an IP Phone, robust internet connectivity, a headphone, and a laptop, and you are all done with VOIP set up.

Although the first VOIP was launched way back in 1995, in the call center it was adapted in the year 2015. especially in India which is the second biggest market after the Philippines in terms of the call center industry, where there are tons of international BPOs but the setup required to call international customers in different geos was very costly hence the need for a cost-effective technology was very much awaited. VOIP revolutionized the call in many ways.

Let’s look at some remarkable benefits of using VOIP in the call center.

Benefits of VOIP in Call Center

Here are 5 main benefits of using VOIP In Call Center

1. Cost-effective :

One of the prime benefits of setting up a VOIP environment in a call center is the cost-effective approach. Traditionally a call center uses PRI lines to call a customer which costs a huge amount of money, especially for international customers. 

Post introduction of  VOIP technology in call centers we have seen a drastic drop in cost-per-call charges, In addition to that VOIP technology requires less maintenance, set up, and manpower which also reduces the labor cost of a call center.

In total reduces the call-per-cost which is calculated by the formula “Total Call Center Costs/ Number of Calls answered”.

2. Support All Channels :

A call center uses different channels to communicate with customers e.g. call, chat, Ticket etc. Thanks to the VOIP technology which also supports all the channels including:

  • Calls
  • Emails
  • Video
  • Chat
  • Voicemail

3. High-Quality Calls:

The other benefit of using VOIP technology is high-quality calls. Often, calling customers in remote locations and international locations in a traditional call center had to compromise with the call quality.

Often, calling using the traditional method, especially in inclement weather resulted in poor call quality, with the adaptation of VOIP technology providing call centers a robust and high call quality even in weather and natural disasters.

4. Video Calls:

Apart from its conventional use for phone calls, VoIP has evolved into a widely adopted video conferencing solution. You might have already experienced VoIP video conferencing without being aware of it. Popular applications like Facetime, Skype, and Facebook, for instance, utilize VoIP technology to deliver seamless video and audio communication.
