Make Your Solutions Hum

To ensure secure and reliable SIP Trunking services to enterprises, Masergy requires the use of an enterprise Session Border Controller (eSBC). The eSBC serves as the VoIP egress/ingress point of demarcation for our converged voice and data solutions. Our fully managed eSBC solutions are delivered on-premise and from the cloud. It's Your Choice.


End-To-End Certification

To ensure seamless integrations and flawless delivery, Masergy maintains end-to-end certification testing with key enterprise grade platforms including:


Experience Matters

Our decades of experience in traditional communications and cloud communications are applied when engineering your Masergy Cloud UC solutions. We’ve carefully selected and tested eSBCs to ensure seamless interoperability with leading platforms including:

  • Avaya Communications Manager
  • Cisco Call Manager
  • Microsoft Lync
  • Mitel
  • Asterisks
  • and a variety of other PBXs

Masergy knows every PBX implementation is unique with different features and options activated. Masergy solves interoperability issues between SIP User Agents (UAs) by means of terminating, manipulating or traversing the SIP with an eSBC.



One size does not fit all. Mix and match solutions across our multiple deployment platforms to optimize your network architecture by location, application environment, and budget.
