Centralized CM with Multi-Location - Design Question

  • 1.  Centralized CM with Multi-Location - Design Question

    Posted 12-28-2018 10:47 AM
    Greetings,

    System information.
    • CM 7.1
    • Duplex servers
    • VMware enviornment
    • Centralized architecture.
    • Remote sites - LSP with G450 & G430 gateways.
    • Mostly H.323 IP Phones.
    Voice Setup.
    1. CM is residing in Data center(DC). All other adjuncts - AES, CMS, ACR, MM, SM, SMGR, SBC & Video Conf servers are also in DC. DC is assigned with NR 1. One G450 gateway also in DC location (NR1).
    2. Twenty Remote Locations with local G450/430 Gateway , LSP server and H323 IP Phones, with local PSTN breakout.
    3. 80% of remote locations are connected by MPLS network & voice subnets are routable within all locations. Hence these locations can call each other.
    4. There are few small but important locations without MPLS connectivity. Their G430/LSP registering to DC via site to site VPN & local PSTN breakout. All H323 IP Phones.

    Question.
    Until now these VPN sites were not required to call any other remote locations but now there is a need for it.
    Creating VPN connection to each location is not practical & MPLS up gradation would also not happen in near time.
    What is the solution in this scenario. Please suggest.
