Telecommunications systems in multi-tenant residential buildings tend to grow without a plan. Over time, lines get added, vendors change, and no one is fully sure what connects to what or what can be safely removed.
In 2020, a twin-tower condominium in Midtown Atlanta brought in CTS to evaluate and upgrade its telecommunications system. The goal was not just to improve phone service. The property needed a system that matched how the building actually operated, supported life safety requirements, and would hold up as carrier infrastructure continued to change.
This became a phased telecommunications system upgrade, not a one-time replacement.
At the time, the building was operating with a setup that looked functional on the surface but had underlying issues.
A VoIP system was handling both daily communications and life-safety connections, which posed a risk whenever their internet service dropped. There was no clear documentation of phone numbers or circuits, so even small changes were difficult. Calls between the two towers were inconsistent, and concierge staff had no way to stay connected when they stepped away from the desk.
The system wasn’t broken, but it wasn’t stable, and it wasn’t positioned for what was coming.
CTS began by determining exactly what was in place.
That meant tracing lines, identifying numbers, and documenting how everything connected. In most buildings, that alone uncovers unused services and unnecessary costs. It also removes the guesswork that usually slows down decision-making.
At the same time, CTS worked with management to understand how the building actually functioned. Two towers, two front desks, shared responsibilities, and constant interaction with residents. The system needed to reflect that reality.
Only after that did the upgrade move forward.
The initial phase focused on making the system easier to use and more reliable without overcomplicating it.
CTS implemented a cloud-based VoIP system with structured call routing, enabling residents to reach the right person without being transferred between desks. Call rollover between towers ensured that calls didn’t go unanswered. Mobile applications allowed concierge and management staff to stay connected anywhere on the property.
Elevator communication was simplified through line sharing, reducing unnecessary circuits while maintaining compliance. Desktop dialing replaced manual processes that slowed staff throughout the day.
The transition was completed without downtime, which alleviated one of the board's main concerns.
The original system held up well, but the industry changed.
As carriers moved forward with the retirement of copper lines, the remaining POTS lines in the building had to be addressed. Because the system had already been organized and documented, this wasn’t a scramble.
CTS migrated those lines in phases, replacing them with supported solutions that met current requirements. By 2025, the building had fully transitioned to a combination of VoIP and cellular-based systems, with cellular backup for life-safety communication paths.
That transition maintained reliability while removing dependency on infrastructure that no longer exists.
The difference is most visible in day-to-day operations.
Concierge staff can answer calls while assisting residents away from the desk. Management can stay connected when off-site. Residents can reach the correct person or security directly without delays.
The system supports the building instead of getting in the way.
There are still capabilities within the platform that go beyond basic use. Features like call routing rules, transcription, and reporting can further improve responsiveness when fully utilized, but even the core improvements have made a noticeable difference.
Telecommunications costs in residential buildings are often higher than they should be, and the reasons are consistent across buildings.
Properties continue paying for lines they can’t identify. Old contracts stay in place long after better options are available.
In this case, cleaning up the environment and aligning services properly reduced monthly costs by about 20 percent while improving performance.
Most delays in a telecommunications system upgrade stem from concerns about disruption.
Boards and managers worry about outages, confusion, and the learning curve for staff. In practice, when the system is built around how the property operates, the transition is straightforward.
Here, staff adapted quickly. Mobile access, direct routing, and simplified workflows were immediately useful.
The building now has a telecommunications system that has been updated in stages rather than being replaced all at once.
It is reliable, aligned with current carrier infrastructure, and easier to manage. Costs are controlled, and future changes can be handled without starting over.
A telecommunications system upgrade in a multi-tenant residential building works best when it is approached as an ongoing process. When the system is understood, documented, and updated at the right time, it becomes stable, predictable, and far less of a burden on management.
