We are excited to share that Sipsynergy and Callroute have joined 8×8.
Callroute is our flagship service built to simplify telephony and connect calling directly into collaboration tools like Microsoft Teams and Webex.
As part of our evolution, Enterprise Hosted Voice (EHC) will be retired, while Business Hosted Voice (BHC) will transition to Callroute’s modern, AWS-hosted cloud platform.
Our mission has always been to empower global enterprises to visualize, simplify, and manage their telephony. By joining 8×8, we are securing the infrastructure required to take that mission to the next level.
8×8 provides the industry’s most integrated platform for Customer Experience – combining Contact Centre, Unified Communications, and CPaaS into one seamless cloud solution.
This acquisition brings together Callroute’s universal orchestration engine with 8×8’s sovereign global network and engineering scale. While we remain committed to delivering the industry’s best Microsoft Teams integration, joining 8×8 allows us to expand our scope significantly.
Together, we are advancing three core capabilities for our partners and customers:
Completing the Microsoft Portfolio: Delivering a single, integrated solution for Teams Phone, Contact Center, and Direct Routing management.
Universal Orchestration: Empowering customers to visualize their entire telephony estate and manage multi-vendor environments with unprecedented ease.
Global Routing: Backing your voice traffic with a sovereign, carrier-grade network foundation.
By becoming part of the 8×8 family, we are reinforcing the tools you trust with deep engineering resilience and long-term stability, without changing the flexibility you value today.
Existing partnerships, services, and points of contact remain unchanged and if you have any questions, feel free to reach out to those contacts.
We are combining our agility with the scale of a global leader to build the future of voice orchestration.
It’s an exciting future. Let’s head there together.
