What Is a VoIP Phone System?


VoIP, which stands for Voice over Internet Protocol, is also known as IP telephony. It's a technology that enables the transmission of voice and various forms of communication over the internet. Many businesses are making the switch from traditional phone services (POTS or PSTN) to VoIP due to its numerous advantages.


A VoIP phone system works by converting voice signals into digital data packets, which are then transmitted over the internet through a router. This technology offers a wide range of features, including voicemail, call forwarding, call waiting, caller ID, and conference calling, similar to traditional office Private Branch Exchange (PBX) systems.


One key advantage of VoIP is its seamless integration with other business applications, such as Customer Relationship Management (CRM) systems, providing a unified source of customer information. Furthermore, VoIP maintains call quality by relying on a stable internet connection, supported by various components like computers, routers, SIP phones, VoIP servers, and VoIP service providers.



The Difference Between a VoIP System and a Telephone Line


Traditional phone systems, whether at home or in an office (POTS or PSTN), utilize hardware running on the Primary Rate Interface (PRI) within the ISDN network. These systems require physical phone cables and a PBX server, allowing more phones than phone lines and offering free calls between users.


VoIP phone systems, on the other hand, come in three varieties: IP PBX, fully virtual VoIP, and hybrid VoIP. IP PBX setups route calls through VoIP networks and the PSTN system interchangeably. Fully virtual VoIP relies solely on the internet and phone system software, eliminating the need for physical phones and cables. Hybrid solutions combine PRI phone systems with IP phones.


How to Choose Between the Two


The choice between VoIP and PBX systems depends on various factors:

  1. Current Setup: If your existing PBX system meets your needs and scaling isn't an issue, sticking with it may be cost-effective.

  2. Internet Reliability: PBX systems use phone lines, ensuring continued communication during internet outages. VoIP forwards calls to another number during internet failures.

  3. Remote Teams: VoIP allows for remote work setups, while PBX limits calls to onsite locations.

  4. Cost: PBX systems have lower monthly fees but incur higher installation and maintenance costs. VoIP offers fixed monthly subscriptions without additional call or equipment expenses.

  5. Features: VoIP provides a broader range of features, including call queuing, recording, routing, and CRM integration, compared to PBX systems.

  6. Sound Quality: PBX systems usually have good sound quality, while VoIP quality relies on a strong internet connection.

  7. Availability: Setting up a new PBX system is costly and rare, whereas VoIP systems can be quickly implemented with a stable internet connection.
