How Does VoIP Work?

Voice over Internet Protocol is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol networks.

Depending on the size of your company and the infrastructure you already have in place, jumping on the VoIP bandwagon could cost your company next to nothing or it could entail significant up-front costs.

VoIP makes it  significantly cheaper than placing your calls through traditional telephone service providers.

  • But is VoIP really all it’s cracked up to be?
  • Are the potential pitfalls worth the potential monetary payoffs?

Generally, things are pretty simple if you’re looking for a hosted service. Many of the top VoIP providers handle all the heavy lifting offsite.  Delivering calls to your phones without much hassle especially if you use phones that are plug-and-play certified for VoIP. The majority require no additional on-site hardware at most you might need to find a space for a small box of hardware somewhere on-site.

In contrast, maintaining a self-hosted, on-site VoIP system requires a bit more work. You need an IP-based private branch exchange—a VoIP-friendly version of the PBX phone systems that many offices use—to route your calls to the appropriate phones on your network, as well as a device called a PSTN gateway.

The PSTN gateway sits between the IP-PBX software and the analog signals of the public switched telephone network converting calls to and from digital signals as necessary.

No matter which option you choose you can handle the basic settings for your phone lines or extensions over the phone.

This can be complex so we recommend that you contact a local service provider to walk you through your options.
