IP-PBX with 3 Universal Slots (GSM-IP-POTS)
IP-PBX with 3 Universal Slots (GSM-ISDN-IP-POTS)
IP-PBX with 6 Universal Slots (GSM-ISDN-IP-POTS)

              All progressive organizations are moving to IP-PBXs for the obvious benefits of flexibility, productivity, integration and cost. While migrating to IP Telephony, it is extremely important to remember two important requirements – Mobility and Connectivity. An IP-PBX without these two functions is like a new-generation car without wheels and navigation. 

            Presenting Matrix ETERNITY – The IP-PBX with Seamless Mobility and Universal Connectivity. 

            Matrix ETERNITY provides true mobility to its users by allowing them to use their mobile phones as PBX extensions. Not only users can make and receive calls, they can also use most of the PBX functions like Transfer, Forward, Voice Mail, Directory and Conference using their mobile phones from within and outside office. This seamless mobility means complete freedom from being tied to your desk for internal or external communication. 

Further, any IP-PBX worth its name should interface with all-pervasive legacy and new-generation wireless telecom networks like POTS, ISDN, T1/E1, GSM, 3G and VoIP. The ETERNITY IP-PBX offers Universal Connectivity with all these networks combining best of both the worlds. Thus, ETERNITY facilitates smooth and natural migration to the new-age IP infrastructure.

Universal Connectivity –The true convergence

                 Matrix ETERNITY IP-PBX offers a true convergence of varied networks. It offers connectivity from traditional networks such as PSTN, E&M, Magneto, ISDN BRI and T1/E1/PRI, wireless networks such as GSM and 3G to new-generation networks such as VoIP including IP trunks and extensions.

Interface Options:

  • Analog CO Lines (TWT)
  • Analog Phones (SLT)
  • Digital Key-Phones and DSS Consoles
  • ISDN BRI (TE and NT Mode)
  • ISDN PRI (TE and NT Mode)
  • T1/E1 (with QSIG)
  • Wireless (GSM/3G)
  • VoIP Server
  • VoIP Trunk Lines
  • E&M
  • Magneto Phones



                       Varied user terminals such as a Soft-phone, Mobile with SIP client, IP Phones, VoIP ATAs and VoIP Gateways can be registered as users to the VoIP SERV+TRK card. Such 999 users can be registered. Extensions to this card can be directly connected through the LAN or connected remotely via internet. Registered users can talk to the system extensions and can also make calls using system trunks i.e. GSM/3G, SIP etc. Resulting in complete portability, convenience and huge savings on telecom cost.
