Binayak group is a leading Real Estate Corporate House providing a wide range of residential and commercial projects from the leading developers. For an upcoming residential project where Binayak had to connect multiple towers, they wanted an IP based Intercom system to minimize cabling costs. Also the communication system had to be scalable for future expansion and manageable from remote location.


The upcoming residential project from Binayak group had multiple towers in single Block. Interconnecting all the towers was a tedious and costly affair. The group required an intercom solution that can suffice below challenges faced:

  • Alternative solution for complex cabling and costs associated with traditional intercom systems
  • Connectivity between two systems and transparent availability of calling features
  • Scalability of system capacity to support future expansion plans
  • Advanced intercom features to map flat to extension numbers, security extensions, security alarm and reporting, paging with Public Addressing System

Matrix along with channel partner – Amtel Communication offered IP based Building Intercom solution. Matrix offered ETERNITY LE and ETERNITY ME – The IP-PBXs for two different blocks with 10+ residential towers in each block. Further, both the blocks were interconnected over IP through optical fiber network which eliminated one-to-one cabling of extensions in both the blocks. This eliminated complex cabling between two blocks and subsequently reduced the cabling cost up to 40%.

  • Block A – 15 Towers each with 50 Flats connected with ETERNITY LE
  • Block B – 11 Towers each with 29 Flats connected with ETERNITY ME
  • Reduced cabling costs by connecting disparate towers over peer-to-peer IP networking
  • Remote management of all systems eliminating personal site visits for configurations or minor changes

  • Reduced up to 40% of cabling cost
  • Residents can communicate quickly between the blocks just by dialing extension numbers
  • Easy to manage and configure the system with web based GUI Open to future scalability plans
