A Comprehensive Guide to Call Center Phones

A call center uses various types of phones, including IP phones, VoIP phones, mobile phones, virtual assistant phones, and traditional landline phones. Call center phone systems are available in both hardware and software forms, each with its own advantages and disadvantages.

Whether it’s a VoIP phone, software, IP desk phone, PBX system, or traditional landline, the choice depends on factors like call volume, budget, and business needs.

IP phones use the internet to transmit calls via VoIP technology, converting analog signals into digital data. When you speak into an IP phone, it converts your voice into digital data packets. These packets are then sent over the internet to the recipient’s phone. The recipient’s phone decompresses the data and plays it as audio.

Most call centers now use VoIP phones. Voice over Internet Protocol (VoIP) phones operate through physical devices that utilize VoIP technology or as virtual phone applications installed on computers or mobile devices. Some examples of IP phones include Fanvil, Snom, Yealink, etc.

Advantage

• Cost-effective when making long-distance calls.
• It allows remote work and scalability.
• Advanced features like call forwarding, call conferencing, call transfer, and video calls.

A 2-line VoIP phone or a multiple-line VoIP phone is similar to an IP phone. However, instead of connecting only two people, it simultaneously connects two different phone numbers, allowing users to make and receive calls on both lines at the same time.

You can have two different phone numbers connected to the same device and switch between them easily. Popular models of 2-line VoIP phones are Yealink and Grandstream.

Advantage

• Connects multiple phone lines to a single device.
• Cheaper compared to traditional lines.
• It can be easily upgraded to accommodate more lines as required; simply add additional lines to your existing device.
• Includes features like call forwarding, voicemail, call waiting, and call transfer.

Traditional phone lines, also known as POTS (Plain Old Telephone Service) or landline phones, have been used in call centers for decades. Many modern call centers have transitioned to VoIP and cloud-based systems, but some businesses continue to rely on traditional phone lines due to their simplicity and reliability.

Landlines are primarily used in traditional or smaller call centers, especially if they have not yet fully migrated to a digital infrastructure. These phones are usually connected to a PBX system. However, landlines are considered more costly than other phones.

Advantage

• A reliable connection, even during power outages and internet disruptions.
• Voice calling, caller ID, call waiting, and call forwarding features are available depending on the models.
• It has clear audio quality.
• Accessible for remote areas with poor internet access.

Unlike VoIP phone systems, mobile phones use cellular networks to make calls. They use an app that connects the mobile phone to the call center’s phone systems. It helps employees to work remotely.

If an employee has the app installed on their phone, for instance, they can answer calls just like they would on a desk phone, whether they are working from home or another location. For example, Skype, Zoom, etc. 
Advantage

• It offers flexibility for agents who need to answer calls while away from their desks.
• It enables agents to work remotely.
• Easy-to-use solution.

Cordless phones, also known as wireless phones, enable agents to move freely while remaining connected to the phone system. They are less common in larger call centers due to their limitations in managing multiple calls at once and the need for consistent connectivity.

Advantage

• Provides flexibility to agents to move around within a specific range while staying connected.
• Easy to set up and an ideal fit for call centers with smaller spaces.

Softphones are applications installed on computers, tablets, or smartphones that enable agents to make and receive calls over the internet, much like a VoIP phone. Agents don’t need a physical phone; they use the app to handle calls, integrate with CRM systems, and manage call data.

Some examples of software include Calilio, OpenPhone, and DialPad.

Advantage

• Reduces hardware costs
• Softphones offer advanced features such as click-to-dial, call forwarding, call conferencing, chat, and many others.

If you already have a phone in place, you'll still need several other components to ensure the smooth operation of your call center. These tools are required to complete the phone system in a call center.

A good call center software is required, regardless of the phone used in a call center, to unify the devices and also to organize the calls. In most call centers nowadays, they handle calls using VoIP-based call center software. This software enables businesses to effectively manage and optimize their customer service by efficiently handling both inbound and outbound calls.

Easy-to-use interfaces reduce the learning curve time, and with minimal training, employees can quickly learn the workflow of the chosen phone system. Customizable features will be beneficial to your specific workflow. However, if you have an experienced team, you can select which one to pair with your call center.

Scalability is key to long-term success, as it ensures a business can meet market demand without failure. You can easily add agents as your business grows. You should choose the system that allows access to new functionalities as needed, without a significant system overcharge.

Your call center’s data is very important. If they are leaked or accessed by an unauthorized person, your business will be compromised. Therefore, you should choose a system that complies with relevant data protection laws and supports the family. Calls should be encrypted to protect sensitive customer information.

Pricing can be a primary factor in determining the best phone system for your call center. First, understand the cost per agent per month for all the phone systems, and then you can select the one that is reasonable for you. Also consider the length of the subscription and potential renewal costs.
