Background

Jason Barthman, representing Sunstream Business Services, sought a unified telephony solution to streamline operations, simplify user experiences, and reduce costs. Jason reached out to CallTower to explore solutions that could integrate seamlessly with Microsoft Teams—a platform already familiar to many of his clients.


Challenge

Sunstream Business Services was using a cloud-based telephony solution alongside Microsoft Teams. This setup created inefficiencies, requiring users to switch between platforms and support staff to manage multiple systems. The primary goals were to:


Approach and Solution

CallTower’s Midwest sales team, led by directors Rafael Renteria and Bryan Green, collaborated closely with Jason to assess his needs and tailor a solution. Together, they determined that migrating to Microsoft Teams as the main telephony platform, supported by CallTower’s expertise as a Teams partner, would provide the most value.

Key Aspects of the Solution:

  1. Seamless Native Microsoft Teams Integration:
    CallTower leveraged Teams to create a streamlined experience for end users, ensuring they wouldn’t need to transition between applications for calling, collaboration, or administrative tasks.
  2. White-Glove Implementation:
    A dedicated project manager provided consistent support and personalised guidance throughout the migration process.
  3. Custom Features and Flexibility:
    CallTower addressed specific needs through native integrations, including SMS, SIP lines for conference rooms, and continued support for analogue devices like fax machines.
  4. Training and Support:
    CallTower delivered expert end-user training tailored to each client. The preferred trainer built rapport and provided ongoing education to ensure users were comfortable and confident with the new system.

Success Outcomes

Jason’s partnership with CallTower has been a remarkable success. To date, he has migrated five financial clients to Microsoft Teams with CallTower’s support, all of whom have experienced improved efficiency and functionality.

Key Benefits:

The consistent use of the same project manager across all migrations created a seamless implementation experience, while end-user training ensured high adoption rates.


Lessons Learned

As a Teams partner, CallTower’s ability to provide industry-specific expertise proved invaluable. Through this collaboration, Rafael and Bryan identified best practises for meeting the unique needs of financial clients, enabling them to replicate these solutions for other organisations in the vertical. From pre-sale discovery calls to post-implementation support, the CallTower team demonstrated a commitment to customization, communication, and partnership.

“From start to finish, the CallTower team truly felt like an extension of our own. The level of communication, expertise, and training they provided was outstanding. They made what seemed like a daunting project into a smooth and successful experience.”
