T3 MSP helped us migrate our server, and now we can access our files much quicker than when we were on the cloud. T3’s team responds quickly to any problems and will do what it takes to correct them when we are down. They understand the cost of being down.
Mark Zerona
Vision Envelope
T3 MSP has helped us out tremendously! Most importantly, the project of moving our sister company email domains under one common location has been a fantastic improvement for our company. T3’s team worked weekends and late hours, many times, to make these projects happen as seamlessly as possible for us. For that and much more, we are very grateful!

The latest project involved our Atlanta warehouse, and I appreciate the personalized support and responsiveness of the T3 team. I haven’t worked with another IT firm in a long time. I have been working with T3 for over 10 years. If you are considering T3 as your IT service provider, just give them a try!! I have NEVER had a bad experience with the T3 team in all these years working with them.

All I can say is that working with T3’s staff has been an outstanding experience: from planning meetings to the installation and follow-up. They are very knowledgeable and consistent with their high quality of work, which gave me peace of mind.

We had a ransomware crisis where we lost access to one of our disks. I emailed T3 MSP on a Sunday, and after two hours of triaging the issue, it became clear what had happened. First, they walked me through every step of the resolution. Then they proposed more robust protection by combining monitoring apps, secured backups and recovery, anti-malware software, and user training. So, we are now working with them on those additional longer-term measures.

What Is Included in Phone Systems Migration
Structured Teams Phone transition support
Readiness Review
Plan Before You Port
A successful phone migration starts with understanding how calls move through your business today. T3 MSP reviews users, departments, numbers, call queues, auto attendants, voicemail needs, licensing, devices, and Microsoft 365 readiness.
The result is a clear migration plan that identifies risks, sets priorities, and reduces the chance of avoidable downtime during the cutover.
Number Porting
Protect Your Numbers
Number porting is one of the most sensitive parts of a phone system migration. T3 MSP coordinates port requests, validates phone number ownership, maps numbers to users or call flows, and schedules the transition around operational needs.
This helps keep inbound and outbound calling organized so your team can continue serving clients with minimal disruption.
User Provisioning
Set Up Users Right
Microsoft Teams Phone works best when every user is provisioned correctly from the start. T3 MSP configures users, calling policies, voicemail, device settings, and access inside Microsoft 365 so calling fits the way each role works.
Clear setup reduces confusion, limits repeat tickets, and gives employees a smoother experience when the new phone system goes live.
Call Flow Setup
Route Calls Clearly
Call routing needs to match real business workflows, not a generic phone tree. T3 MSP builds and tests auto attendants, call queues, routing rules, voicemail options, and escalation paths based on how customers and internal teams actually communicate.
That planning helps calls reach the right person faster and supports better service continuity after migration.
Quality Support
Improve Call Quality
Phone quality depends on more than the phone platform. T3 MSP reviews connectivity, devices, network conditions, user reports, and configuration settings to help identify issues that can affect call clarity or reliability.
Post-migration support includes practical troubleshooting for dropped calls, device behavior, Teams Phone settings, and user adoption challenges.
User Training
Support User Adoption
Even a well-built phone system can struggle if users are not prepared. T3 MSP provides guidance for Teams Phone features, calling workflows, voicemail, transferring calls, and day-to-day use inside Microsoft Teams.
After cutover, users can access responsive support during business support hours, with weekend support from 9am – 4pm for issues that need attention.
