Facilitating seamless user migration while saving costs

How Sipcom improved a global company’s ability to focus on strategic tasks, ultimately leading to improved outcomes for their organization.


A leading global financial services company is undertaking an initiative to modernize its telephony solution by transitioning to Microsoft Teams.

This strategic move is driven by the company’s commitment to enhance its unified communication strategy and embrace digital transformation. As the organization is part of the financial sector they require a solution that is highly secure and in a tightly controlled environment compliant with the stringent regulations of the US financial sector. The company aims to execute a seamless migration with zero downtime and also leverage its existing carrier services with whom they are still in contract. As the company has a global presence, they are receiving preferential rates from its current carriers and as such cannot move away from its existing providers.

Business challenges

In light of the specific requirements of Customer B’s business, they require a highly secure and tightly controlled environment that adheres to the regulations set forth by the US Financial sector.

Customer B’s requires no downtime between the move from their legacy PBX to Microsoft Teams.

Customer B currently maintains contractual agreements with several international carriers, capitalizing on their business scale to secure advantageous rates. Transitioning to an alternate service provider would potentially entail early termination penalties, which could lead to higher calling expenses and an associated rise in operational costs for Customer B.

Our solution

Sipcom deployed Customer B’s solution using the HALO platform. This platform is a secure, global cloud architecture that is owned, managed, and maintained by Sipcom. The solution is a highly available, latency-optimized infrastructure that enabled Customer B to meet all resilience, regulatory, and compliance requirements.

By deploying Customer B’s new Microsoft Teams solution using Sipcom’s Bring Your Own Carrier (BYOC) offering, Sipcom was able to leverage Customer B’s existing relationships by routing Microsoft Teams to their existing Carrier. By deploying the solution this way, Customer B was able to avoid any costs involved in canceling current contracts and continue to benefit from the preferential rates.
