What are Analog and VoIP Phone Systems?
In the ever-changing world of telephony, many businesses and organizations may find themselves exploring different methods for facilitating their phone services. For decades, many businesses have been relying on traditional analog PBX (Public Branch Exchange) systems while some have transitioned to newer VoIP PBX systems.
Analog Phone Systems
Analog phone systems utilize copper wires, and other cabling mediums, to transmit calls through an on-site PBX system or a Plain Old Telephone Service (POTS) network that relies on circuit switching to direct calls. These copper wires are commonly referred to as phone lines. Analog phones that rely on physical lines are often referred to as landlines.
Quick Tip: An individual that is using an analog phone has a single phone line connected that can host one call. To allow multiple calls to be made at once, additional phone numbers with dedicated phonelines are required.
VoIP Phone Systems
Unlike analog phones, phones that use VoIP services can place and receive calls as long as they have a power connection and a stable internet connection. This can make using VoIP much more cost-effective and convenient in contrast to analog services.
Quick Tip: VoIP phones use a virtual extension number to place and receive calls. A virtual extension can be created and assigned to a seat (also known as a User). A User can have multiple devices registered to their extension number. With a virtual extension, multiple calls can be handled concurrently on a single device as long as the device has available line appearances (also known as lines).
Adding more virtual extensions, or seats, for users is easier and more convenient since they can be configured virtually without the need for an on-site technician visit.
As the world becomes increasingly digital while analog infrastructure degrades, investing in VoIP technology offers the potential for continued innovation and improvement in communication technology.
What is the Difference?
Analog and VoIP phone systems differ in their underlying technology, infrastructure, features, and how they transmit voice communications.
While analog phone systems have been the traditional choice for voice communication, VoIP phone systems offer advantages such as cost savings, scalability, advanced features, and integration capabilities. However, considerations such as reliability, voice quality, and regulatory compliance may influence the choice between analog and VoIP systems for specific use cases.
Technology
Analog Phone Systems
Analog phone systems transmit voice signals over traditional copper wire circuits using electrical signals. Analog phones convert sound waves into electrical signals, which are then transmitted over the Public Switched Telephone Network (PSTN) via circuit-switching.
To allow multiple calls to be made at once, additional phone numbers with dedicated phonelines are required.
VoIP Phone Systems
VoIP phone systems transmit voice signals over the internet using SIP messaging. Phones that use VoIP services can place and receive calls as long as they have a power connection and a stable internet connection.
With a virtual extension, multiple calls can be handled concurrently on a single device as long as the device has available line appearances (also known as lines).
Infrastructure
Analog Phone Systems
Analog phone systems require a dedicated network of copper wires, switches, and exchanges managed by telecommunications companies. These systems are typically based on circuit-switched technology.
One reason many businesses and organizations are making the move to VoIP services is the increasing cost of installing and maintaining copper lines. As many copper-based infrastructures are aging and degrading, many analog providers are starting to decommission traditional copper wire telephone networks altogether.
Some businesses may have invested heavily in legacy analog phone systems and infrastructure. Organizations experiencing this dilemma can consider exploring integrating their systems with VoIP services or transitioning away from analog devices.
VoIP Phone Systems
VoIP phone systems rely on existing internet networks and network devices. VoIP systems can operate on the same network infrastructure used for data transmission, or computer and phones can be connected to separate circuits for bandwidth management purposes.
When using VoIP services, it is recommended to make sure that your network's router and any firewalls are configured to facilitate and prioritize VoIP calls.
Analog Telephone Adapters (ATA) and SIP Trunks can be solutions used to allow legacy phone systems to integrate with SpectrumVoIP services.
Features
Analog Phone Systems
Traditional analog phone systems offer basic features such as call forwarding, caller ID, voicemail, and conference calling. Advanced features may require additional hardware or services.
VoIP Phone Systems
SpectrumVoIP offers a wide range of features, such as voicemail-to-email transcription, call routing, auto-attendants, video conferencing, VoIP faxing, and integration with other business applications like CRM software.
With SpectrumVoIP, you can utilize a desktop app and mobile app (For Stratus users: the StratusHUB Desktop App and our SpectrumVoIP Stratus Mobile App) (For ES users: the ES Desktop App and the SpectrumVoIP ES Mobile App) for handling calls. This mobility is particularly useful for businesses with teams that work remotely.
Cost
Analog Phone Systems
Analog phone systems typically involve higher setup and maintenance costs. Analog customers may see costs for line rental, long-distance calls, and hardware upgrades.
VoIP Phone Systems
Since the use of VoIP depends on existing internet infrastructure, transitioning to a VoIP phone system can be cost-effective. Certain equipment, such as routers, switches, adapters, and headsets, can be bought to help enhance your experience with your phone system.

Our VoIP services transcend geographical boundaries, making it easier and more cost-effective for businesses to communicate with clients, partners, and employees worldwide. You may also see lower costs for both domestic and international calls compared to some traditional analog services. Traditional analog services may incur significant costs for international calls.
Scalability
Analog Phone Systems
Adding more analog landlines requires an on-site installation of physical cabling by a technician, which can be expensive and interruptive for businesses.
VoIP Phone Systems
Adding new seats, or users, is convenient since our team can virtually configure them. Installing and registering new phones and devices can also be done virtually with the help of a SpectrumVoIP support team member.
As an on-site technician is not typically necessary for adding seats or registering new devices, expansion is typically more flexible and cost-effective compared to analog systems.
Reliability
Analog Phone Systems
In areas with poor internet connectivity or high levels of network congestion, using analog services may be more reliable and provide more consistent voice quality; however, traditional analog infrastructure may be more susceptible to disruptions caused by natural disasters or infrastructure failures.
Traditional analog phone lines are still being used for certain emergency services, such as fire alarm systems, security alarm systems, elevator phones, and more. In certain industries or regions, there may be compliance standards that require the use of analog phone lines for specific purposes, such as financial transactions or healthcare communications. Following these regulations may necessitate the use of analog services instead of VoIP.
VoIP Phone Systems
The reliability of your VoIP phones is influenced by the quality of your business' internet connection and network infrastructure.
Our VoIP system has built-in redundancy and failover mechanisms, ensuring high availability and minimizing downtime. Traditional analog services may be more susceptible to disruptions caused by natural disasters or infrastructure failures.
