Microsoft Phone System

Harness the power of the human voice

Combine your phone system with your cloud system.

Telephony in a modern technology environment

Microsoft Phone System extends Microsoft Teams with the capabilities business used to gain with a private branch exchange (PBX), but without forcing companies to invest in costly hardware that requires specialized management skills. Once Phone System has been deployed and configured for you, telephony becomes part of your technology management portfolio and does not require specialized expertise.

From within the Teams environment, users can rely on Phone System to initiate, receive, and transfer calls, using their mobile devices, a headset connected to a computer, or a purpose-built IP phone. All users within your organizational domain can communicate internally through Phone System, no matter where they are geographically. Phone System can connect to public telephone networks by accessing your existing telephony hardware or through a cloud-based Microsoft Calling Plan, which you can obtain through Sikich.

Efficient deployment managed by Phone System experts

Sikich has deployed Microsoft Phone System for many clients with very different business conditions. In Phone System projects, we combine our Teams expertise with the framework of Practical Guidance for Cloud Voice to shorten the time-to-benefit with an efficient implementation. Your Phone System delivery is in the hands of Sikich certified engineers and Teams experts.

We maintain a fast momentum both in new deployments and in migrations from older Microsoft phone and conferencing technology. Over the course of dozens of engagements, we have found the most effective ways to configure Phone System to meet your requirements for emergency calling, port existing phone numbers, route calls, enable paging, and make the best use of your network resources.

We can deliver Phone System with high-quality sound over public internet connections through our SD-WAN partnership with Bigleaf. In addition to providing you with all the Phone System functionality you need, we aim to keep your technology environment streamlined and easy to manage.


A Sikich Phone System implementation can be part of your Microsoft 365 and Teams deployment or other, transformative technology changes. Alternatively, we can focus on Phone System exclusively.

We typically begin Phone System assignments with a network assessment, which allows us to plan and design your solution, which we configure and deploy to your users. We hand over a clean, smoothly running voice-based communication solution, and work with your teams to make certain that people are comfortable with Phone System and will use it consistently.

Depending on your preference, we can step away as you assume everyday management or wrap ongoing support and maintenance for Phone System into a Sikich IT managed services agreement.
