Call center phone

What phones do call centers use?

Call center agents answer questions, listen to complaints, and provide support to customers. To be able to do this effectively they need the right equipment.

Call center phone systems include both hardware and software. Each one has its advantages and disadvantages.

Here are some of the most common types of phone systems that call centers use.

IP phones (VoIP)

IP phones, VoIP, or SIP phones are phones that work via the Internet. These phones convert analog signals into digital and send them as data. You can use your smartphone and transform it into a SIP phone via an app. Or you can download a desktop app and use your laptop.

VoIP phone (2-line VoIP phone)

A 2-line VoIP phone or multi-line VoIP phone is similar to an IP phone. However, instead of connecting only two people, they allow multiple lines – several devices can be attached to a single line. This is very useful in call center environments.

Mobile phone systems

Lots of call centers use mobile phones to conduct their business. They usually use an app that connects the device to the system. This approach gives more flexibility and allows employees to answer calls remotely.

Virtual assistant phones

These phones can also be landline or Internet-based – the key difference is that they come with virtual assistants or receptionists. You can record answers, greet people, and let them choose the department they need to contact depending on their inquiry.

Traditional phone lines

Also called POTS (Plain Old Telephone Service) or landline phone, these traditional local lines are outdated, but they are reliable and easy to use. They work on analog lines, and you can hook them to typical telephones, but there are also options to connect them to PBX or VoIP systems.

What equipment do you need for a call center?

Running an efficient call center requires more than just a phone system. Modern call centers use various equipment and technology to perfect their services and improve operational speed.

Desktop computers and laptops

These are used for inbound and outbound calls just like any other telephony service. They require reliable call center software like LiveAgent to manage and further streamline calls.

Call center agents often have to perform other tasks apart from talking to clients. They can resolve tickets, update CRM, etc. if they have a computer available.


Even though call center environments can have up to dozens of people in a single room, it’s essential to have clear communication with clients. That’s why old phone receivers are not good enough – each agent needs to have a headset with a microphone.

Consider whether you will get Bluetooth (wireless) headset or a USB headset.

Wireless headsets offer more accessibility and less disruption. Customer service agents can walk around the office while talking. However, they need to be charged. On the other hand, USB headsets don’t need charging, but they limit movement.

Ultimately, you need to decide what type of headset will work best for your call center.


The price of a headset with a microphone can range from around $25 up to $400 and sometimes even more. It’s essential to use headsets that have noise-canceling microphones. It ensures that customers will always hear your agents.

VoIP/SIP Phones

Although you can use different phone systems, VoIP or SIP phones are the current standard, and the majority of modern call centers use them.

For call management and setting up lines, the “SIP” Open Standard is used. Voices are transmitted using an IP network to RTP. VoIP phones offer many advantages, including:

  • reduced costs – Compared to landline phone systems, VoIP phones cost on average $30 less per month. Upgrading to VoIP systems is cheaper due to “SIP Trunking.” This protocol lets organizations keep their current hardware while digitizing their voice services.
  • better scalability – It’s easy to scale with these phone systems as they don’t require installing new dedicated hardware or phone lines. A call center only needs to add another phone and “plug it” into the system.
  • softphone support – With a cloud-based SIP system, you can make or receive calls from anywhere, as long as you have a stable Internet connection. These systems support softphones (mobile phones). You can easily use your smartphone simply by installing a dedicated app.
  • improved voice quality – VoIP systems have no call drops and they are clear and crisp. However, to get the full potential of your HD voice, you must meet the bandwidth requirement and implement a robust and reliable network.

Call center software

Call center software is integral for the operations of a call center. It helps organize and manage interactions with customers, as well as monitoring leads, reporting calls, and managing phone calls.

All the interactions are monitored and stored within the CRM. This software also lets organizations create customer profiles to keep important information about them at hand. You can store a client’s phone number, email address, location, details about previous interactions, etc.

Apart from streamlining all the daily processes within the call center, it also synchronizes outgoing and incoming calls, tracks, and routes calls to agents.

Benefits of call center software:

  • better reportingCall center managers can evaluate agent productivity, average handle time, call revenues, upsell rates, and other vital data.
  • higher query resolutions – Many call centers serve as customer support hubs. IVR routes calls based on the services, products, customer’s location, and spoken language to find the best-fitting agent.
  • increased efficiency – when call center agents use call center software, their response time to both outbound and inbound calls improves. It also simplifies their daily tasks, allowing them to concentrate on communication with customers.

Help desk software

In customer-centric organizations like call centers, it’s important to give the best possible service. By utilizing reliable help desk software call centers can improve their services even further.

The help desk is a bundled service software that allows call center agents to deal with many different customer queries including complaints, information requests, service requests, incident reports, etc. Help desk software records multiple forms of contact, including calls as tickets.

Here are some of the main benefits of using help desks:

  • fast resolutions of customers’ issues – for each new issue, a ticket is created for an agent to work on
  • increased productivity – agents can effectively assist, analyze, log, and manage help desk tickets
  • availability and data – they allow customers to resolve their inquiries either using self-service or by contacting a customer support representative
