VoIP Calling: The Advantages Outweigh the Disadvantages

New businesses today have abandoned the public switched telephone network (PSTN) in favor of voice over IP (VoIP). With VoIP, software converts analog speech into digital packets that are sent as data over the internet.

VoIP telephony has several advantages over the older generation of voice over copper wires.

  • Cost-efficiency: VoIP services are less expensive than traditional phone lines. They’re just network connections, which means long-distance and international calls are no more expensive than calls across the street. While you can use desktop phones for VoIP calls, you don’t have to — that’s another savings. And VoIP services include features like caller ID, call waiting, and voicemail that traditional providers may charge for separately. Some VoIP providers offer features that old-school providers can’t, such as speech transcription.
  • Scalability: It’s easy to add or remove VoIP lines — all it takes is a few clicks on a configuration console. That’s a big benefit for seasonal businesses, whose usage varies over the course of a year, while growing businesses can start small and expand as they grow.
  • Resilience: In the event of a power outage or natural disaster at your primary place of business, you can easily redirect numbers to other locations or mobile devices.
  • Flexibility: People with VoIP lines aren’t tied to a single location or a particular phone. They can take calls wherever they are, and on just about any networked device — laptop, smartphone, or dedicated IP phone. That’s a benefit for everyone in the organization who makes or receives calls. It’s especially useful for businesses with remote workers or multiple locations.
  • Integration: In many cases, businesses can integrate VoIP lines with other business applications to improve workflow and enhance customer experience.
  • Voice quality: Twenty years ago, VoIP calls often had lower voice quality than phone connections. Today’s VoIP services provide voice quality that’s as good as or better than traditional phone lines, provided there’s a good internet connection.

That last bullet raises an important point. While VoIP has many advantages, it relies on a company’s internet connection. Businesses looking to implement VoIP need to make sure they have a robust, stable, and speedy connection to get the best performance from their VoIP system.

For robust VoIP, choose SIP trunking

One of the most popular ways to get VoIP services is via SIP trunking. Session Initiation Protocol (SIP) an international standard for voice communication over data networks. Trunks used to be physical links — copper wire installed by phone companies from their central offices to customer premises. Nowadays the term also refers to virtual lines of communication.

With SIP trunking, organizations can make calls over the internet to anyone with a phone number. Thanks to all of the advantages of VoIP communication enumerated above, SIP trunks are replacing physical phone lines virtually everywhere.
