Call Center Phone Systems, Microsoft Teams v. RingCentral

Introduction - Today's Best Call Center Phone Systems


Microsoft Teams Phone System

Microsoft Teams Phone System is a collaborative communications app that serves as a home base for your team to stay connected, up-to-date, and engaged on projects.

RingCentral Intro

RingCentral is a cloud-based program that offers a phone call center, video conferencing, and instant messaging through one integrated system.

Microsoft Teams Phone System

Microsoft Teams Phone System offers the same qualities of Private Branch Exchange (PBX) within the Microsoft 365 cloud.

Phone System works with Teams members and recognized devices, handling calls internally within the system and avoiding long distance fees for internal calls.

For external calls, add-on options are available by connecting Phone System and the Public Switched Telephone Network (PSTN).

Microsoft Teams Security Features


Microsoft Teams Phone System Features

Phone System covers all the basics of making, receiving, transferring, muting, and unmuting calls within the same collaborative space that video calls, messaging, sharing and storing documents with your team, and more, take place.

The call center system can be accessed via mobile device, laptop or PC, or any other device that works with Teams, with the ability to transfer between devices during a call without interruption. 

Phone System offers caller ID and spam call identification, Apple CarPlay support, one-to-one call record and transcription, and a relatively new walkie-talkie-like function on desk phones to allow for quick contact between colleagues.

Other features include cloud auto attendants, call ques, default or custom music on hold, call forwarding, call park and retrieve, integrated search bar and dial pad, call blocking, and cloud voicemail. 

(Features list below directly from Microsoft)

Phone System feature


Cloud auto attendants

Lets you create a menu system that enables external and internal callers to locate and place or transfer calls to company users or departments in your organization.

Note that users do not need to be voice enabled to receive calls from the auto attendant dial by name, dial by number directory search. Users do need to be voice enabled to receive calls from the auto attendant menu options.

Cloud call queues

Lets you configure how call queues are managed for your organization: for example, set up greetings and music on hold, search for the next available call agent to handle the call, and so on.

Note that users do need to be voice enabled to receive calls from a call queue.

Music on hold

Plays default music defined by the service or custom music uploaded by the tenant administrator when an external call from the Public Switched Telephone Network (PSTN) is placed on hold. This feature works for one-to-one PSTN-to-Teams calls in addition to calls made to a call queue. This feature provides on-hold notification parity with other platforms.

Call answer/initiate (by name and number)

Lets users answer inbound calls with a touch, and place outbound calls either by dialing the full phone number or by clicking a name in the client.

Call forwarding options and simultaneous ring

Lets users set up forwarding rules so calls can go with them anywhere, or calls can be forwarded to colleagues or to voicemail.

Group call pickup and forward to group

Lets users share incoming calls with colleagues so that the colleagues can answer calls that occur while the user is unavailable. Less disruptive to recipients than other forms of call sharing (such as call forwarding or simultaneous ringing) because users can configure how they want to be notified of an incoming shared call.

Transfer a call and consultative transfer

Lets users transfer calls to another person. Or, if they need to leave their office but want to continue the conversation, they can transfer the calls from their PC or IP phone to their cell phone.

Note that users do not need to be voice enabled to receive transferred calls from another user.

Transfer to voicemail mid call*

Lets users transfer to voicemail during a call.

Call park and retrieve

Lets users place a call on hold in the Teams service in the cloud. When a call is parked, the service generates a unique code for call retrieval. The user who parked the call or someone else can then use that code and a supported app or device to retrieve the call.

Call phone number from search

Lets users place a call from the search box by using the /call command and specifying a name or a number.

Caller ID

Calls from inside the company display a detailed caller ID that pulls information from the corporate directory, showing picture ID and job title instead of just a phone number. For calls from external phone numbers, the caller ID as provided by the phone service provider is displayed. If the external phone numbers are secondary numbers in the corporate directory, then the information from the corporate directory will be displayed.

Device switching

Lets users play a call or meeting on another HID device that is connected to Teams; for example, switching from their PC speakers to a headset.

Presence-based call routing

Controls inbound communications with presence, enabling the user to block all incoming communication except from those specifically indicated.

Integrated dial pad

Lets users dial by name or by number anywhere in the search bar and in the dial pad, speeding up the process of making outbound calls.

Federated calling

Lets users securely connect, communicate, and collaborate with users in federated tenants.

Make and receive a video call

If the user's account is enabled for video calls, the user can make face-to-face video calls with their contacts. All they need is a camera, their computer’s speakers and microphone. Users can also use a headset if their computer doesn’t have a built-in audio device.

Cloud Voicemail

When a user receives a voicemail, it is delivered to their Exchange mailbox as an email with the voicemail message as an attachment. Users can listen to their messages on their certified desktop phone, and on all Teams or Skype for Business applications. Support for voicemail transcription has been added as of March 2017 and is enabled by default for all organizations and users.

Note that users do not need a Phone System license, nor do they need to be voice enabled to use Cloud Voicemail features.

Cloud Voicemail user settings

Lets users configure their client settings for voicemail greetings, call answering rules, and greeting language, including out-of-office greetings.

Note that users do not need a Phone System license, nor do they need to be voice enabled to use Cloud Voicemail features.

Secondary ringer

Users with multiple speaker devices connected to their PC can choose to set a secondary device to ring in addition to their default speaker. For example, a user with a headset connected to the PC and desk speakers can choose to have both headset and desk speakers ring when a call comes in so that they don’t miss a call.

Distinctive ring alerts (Teams only)

Lets users choose separate ringtones for normal calls, forwarded calls, and delegated calls so they can distinguish the type of call.

Shared Line Appearance

Lets users share their phone line so that another user can make and receive calls on their behalf.

Busy on Busy (Teams only)

A calling policy that lets you configure how incoming calls are handled when a user is:

  • in a call
  • in a conference
  • has a call placed on hold.

The caller will receive one of the following responses:

  • hear a busy signal when the callee is on the phone
  • will be routed accordingly to the user's unanswered settings. One option lets the caller leave a voicemail for the user who is already on a call.

The callee gets a missed call notification but isn't able to answer incoming calls. This feature is disabled by default, but can be turned on by the tenant admin.

Call blocking

Lets users add (PSTN) phone numbers to a blocked list so that the next call from that number is blocked from ringing the user.

Common Area Phones

A common area phone is typically placed in an area like a lobby or conference room making it available to multiple people. Common area phones are set up as devices rather than users, and can automatically sign into a network.

Media bypass support (for Teams Direct Routing only)

For better performance, media is kept between the Session Border Controller (SBC) and the client instead of sending it through the Phone System.

Unassigned number routing

Allows routing of unassigned numbers to users, auto attendants, call queues or a custom announcement.


Microsoft Teams Phone System Pricing

Phone and video calls to other Microsoft Teams members are free of charge, but if you want to be able to contact regular phones and don't have an existing service provider, you need to purchase a Calling Plan. 

A calling plan provides customers with a primary phone number and calling minutes to make and receive phone calls. 

Understanding Microsoft Teams Phone system pricing can be a little complex because of various ways to connect your PSTN to Teams. 

Your calling plans will differ depending on whether you’re accessing calling functionality directly from Microsoft Teams or a Direct Routing or Operator Connect provider.

Calling Plans options:

  • Domestic Calling Plan: Licensed users can call numbers located in the country/region where they are assigned in Microsoft 365 or Office 365.
  • International Calling Plan: Licensed users can call numbers located in the country/region where they are assigned in Microsoft 365 or Office 365 and to international numbers in nearly 200 countries/regions. 

Users in the same country/region (as designated in the licensing area of the Microsoft 365 admin center) with the same Calling Plan share a pool of minutes.

For example, if you have 100 users located in the same country/region with a 120 minutes Domestic Calling Plan, they share a pool of 12,000 minutes. All calls exceeding these minutes are billed per minute.

Pricing ranges from $8 per month per user to $57 per month per user based on the plan and existing Microsoft business license being used. Exact features vary based on the plan and can be found here: Microsoft Teams Phone Pricing

For discounted pricing, use a trusted Microsoft Gold Partner and award-winning Managed Services Provider (MSP) like Datalink Networks.

Microsoft Teams Phone System Migration & Setup

The prerequisites for using this phone system are as follows:

  • Microsoft Business Voice license – Activate from the 365 admin center

  • A calling plan – Available starting at $15 per user per month for the Microsoft Teams Phone with a calling plan package

  • PSTN connectivity – Instead of buying phone numbers from Microsoft under the Calling Plan, you can stay with your existing PSTN carrier

  • Direct Routing – Microsoft 365 Phone System with PSTN requires direct routing to connect the public network and the cloud

Microsoft Teams Phone System and RingCentral are two of the best enterprise phone systems available on the market today. Both systems offer very similar functionality and additional features.

As a standalone service, RingCentral has the slight edge. However, Microsoft Teams Phone System is an add-on to the expansive Microsoft Office 365 suite. 

Our recommendation is, if you are already a Microsoft office customer, use the Teams Phone System, but if you are not currently using Microsoft, it is worth pricing out the RingCentral system.
