HMP - miltiple virtual board

  • Hello,

    How can i have multiple virtual boards ?

    I want to register my application with 2 SIP accounts (1 outbound and 1 inbound). how can i proceed ? do i need multiple virtual boards ?

    if yes, how can i proceed.


  • Hi,

    Are you looking to split up the inbound and outbound traffic to two separate ports (o rip address) on the local HMP system?

    As that would be a little different than registering tow different account with a remote SIP REGISTRAR where it may direct traffic to.


  • Hi,

    thank you for your reply.

    Yes, i want to split up inbound and outbound traffic into two separate ports on the local HMP system.

    Best regards

  • Ok, if that is the case then you need to define multiple VBs in this case. Something like the following:


    Where BOARDS_NUM is the amount of boards to use:



    Then make sure you specifically assign unique info for these params:




    And half the channels from what is available in the license for the calls settings:



    but twice for each element in the array. For more info refer to GC IP TUG for IP_VIRTBOARD section on specific params from the HMP bookshelf.
