Configuring Polycom DMA for integration with Pexip Infinity

This section lists the tasks required to configure DMA so that it can be integrated with one Pexip Infinity Conferencing Node in a single location:

This guide is based on Polycom DMA 6.x. If you are using other versions of DMA, you will need to perform the same set of tasks, but the menus and options may differ slightly from those described here.

Setting up a SIP peer

In this step we configure a single Pexip Infinity Conferencing Node as a SIP peer in DMA.

  1. From the DMA web interface, go to Network > External SIP Peer.
  2. From the Actions panel on the left, select Add.

    The Add External SIP Peer dialog opens.

  3. From the panel on the left, select External SIP Peer and complete the following fields:

    Enabled Select this option.
    Name Enter a name for the peer. This example uses Pexip Infinity Node_1.
    Description You can optionally enter a description.
    Next hop address Enter the DNS name or IP address of the Pexip Infinity Conferencing Node.
    Port

    This depends on what you select in the Transport type field below:

    • For TLS, enter 5061
    • For TCP, enter 5060
    Use route header Select this option.
    Type Select Other.
    Transport type Select TLS (if supported); otherwise select TCP.
  4. From the panel on the left, select Domain List. This can be left blank.
  5. From the panel on the left, select Postliminary and complete the following fields:

    Use Output format Select this option.
    To header options
    Copy all parameters of original “To” headers Select this option.
    Format Select Use original request’s To.
    Request URI options
    Format Select Use original request’s URI (RR).
  6. Select OK.

Adding a dial rule

In this step we add a dial rule that routes all calls starting with meet. to the Pexip Infinity Conferencing Node that we have just added as a SIP peer.

  1. From the DMA web interface, go to Admin > Call Server > Dial Rules.
  2. From the Actions panel on the left, select Add.

    The Add Dial Rule For Authorized Calls dialog opens.

  3. From the panel on the left, select Dial Rule and complete the following fields:

    Description Enter a description. This example uses Route calls starting with "meet." to Pexip Infinity.
    Action Select Resolve to external SIP peer.
    Enabled Select this option.
    Available SIP peers Select the Pexip Infinity Conferencing Node added earlier and add it to the list of Selected SIP peers.
  4. From the panel on the left, select Preliminary and complete the following fields:

    Enabled Select this option.
    Script Enter a DMA script that will match the calls you want to route to Pexip Infinity. In this example, we want to match all calls starting with meet. so we use the following script:
    if(!DIAL_STRING.match (/sip:meet.*/))
    {
      return NEXT_RULE;
    }
  5. Select OK.

Note that an alternative approach to using a dial rule if, for example, you are not limited to specific call scenarios, is to make use of DMA's default dial plan and to assign a dial string prefix to the SIP peer instead (as per the H.323 gatekeeper example below).

Setting up an H.323 gatekeeper

In this step we configure a single Pexip Infinity Conferencing Node as an H.323 gatekeeper in DMA, and configure it so that all calls starting 555 are routed to that Conferencing Node.

  1. From the DMA web interface, go to Network > External Gatekeeper.
  2. From the Actions panel on the left, select Add.

    The Add External Gatekeeper dialog opens.

  3. From the panel on the left, select External Gatekeeper and complete the following fields:

    Enabled Select this option.
    Name Enter a name. This example uses Pexip Infinity Node_1.
    Description You can optionally enter a description.
    Address Enter the DNS name or IP address of the Pexip Infinity Conferencing Node.
    RAS port Leave as the default 1719.
    Prefix range

    Enter the numeric prefix used in your dial plan for Pexip Infinity services. This example uses 555.

    Strip prefix Leave this box unselected.
  4. Select OK.
