Types of VoIP Intercom Systems

The types of VoIP intercom systems are:

1. Hardware IP-based telephone system

This type of VoIP intercom phone system uses the company’s computer and is placed in a room with other tech equipment. It has IP phones hooked up to the computer through the building’s local network or even from far away using a more extensive network. The phones can call each other like an intercom does. 

If you need an intercom by a door, many companies also make gadgets that plug into the phone system. When someone pushes the button, it calls a particular person or group of people instead of making a regular call. So it works just like a phone, but only when someone comes to the door.

2. Cloud-based IP telephone system

With this system, instead of buying the equipment upfront, you pay a monthly fee to use an online service. The phones connect over the Internet to a server in a data center somewhere else. The features are the same; you can use SIP door intercoms just like the equipment system.

There are intercoms for multiple tenants that use a service like this. A multi-tenant intercom is at the doors of places with many people, like apartments, condo buildings, or office suites. When someone comes to the door, they pick who they want. You can buy the hardware for the door and then pay a monthly fee per user for the online service that provides features over the internet, like hosting video calls with this system.

3. Self-Contained IP-Based Intercom System

This type of system doesn’t need an online hosting service or computer server hardware. One of the stations has its own website to control a system with up to 32 stations (or more if you pay extra). This system comes with or without a built-in video camera. These intercoms have excellent, loud sound quality, even with noise canceling. 

Since the system can work on its private network, it doesn’t require internet access. By now, you should know what an IP intercom is and how it works. In the next part, we’ll talk about the real-life applications of VoIP intercom systems.

This means they can receive important calls from customers or supervisors even while on-site or traveling between locations, ensuring smooth communication regardless of their whereabouts.

Workers can choose their favorite device, such as a smartphone or tablet, to use. This way, even if they’re moving around on a job site, they won’t miss any important calls.

Choosing the Best VoIP Intercom System for Your Business

When picking a VoIP intercom for your business, you must consider some important things. The intercom needs clear speaking so people can hear each other well. It also needs to work reliably all the time since businesses count on their phones. 

Here are some additional things you should look out for before choosing a VoIP intercom system:

  • Check your internet – Make sure your connection is fast enough for clear VoIP calls before looking at providers. Speed is important for quality service.
  • Decide what features you need – Do you want call forwarding, caller ID, conference calls? Figure out what’s essential for talking with employees and customers.
  • Research providers – See what options are available and look at their experience level, features offered, cost, and reviews. Find one that fits your business needs.
  • Does your equipment work with them? – Providers should say what devices they support, like phones and routers. Or they can test compatibility to avoid issues.
  • Ask about call quality – You want clear calls, so ask how providers ensure this and what they do if problems occur. Good customer service is important, too.
  • Guarantee satisfaction – Look for money-back offers to safely try a provider without risks if you don’t like the service.
  • Consider traffic handling – Traffic prioritization features are the best way to prevent call interruptions, even during peak times.
  • Disaster recovery plans – Know backup strategies if outages happen due to emergencies so you can get back to business fast.
  • Local numbers – Make sure numbers are local so customers don’t pay long distances to contact you.
  • Emergency call support – E911 should work properly to get help quickly in case of emergencies.
