KB122: How and where do I configure VOIP interfaces (gateway, gatekeeper)?

    
 
Information in this article applies to:   VTALL 

Overview

  To configure your VOIP interfaces follow the steps below:
  1. Go to Tools / Options…to display the Options window
  2. Select the Calling Options tab
  3. You will be asked to make the following configurations and choices:
    • Gatekeeper - By typing an IP address or URN in the address field for the gatekeeper you are enabling it to place calls to other H.323 terminal devices. Gatekeepers provide call control; bandwidth allocation, call routing and IP address translation to its registered endpoints. If there is more than one gatekeeper on a network, the user can force VTALL to register with a specific gatekeeper instead of the default one that the application discovers.
    • Gateway – By selecting the check box and typing in your TFTP Server address you enable your Virtual Terminal to use H.323 gateways to bridge voice over IP calls to the public telephone network. Gateways use hardware and associated software to connect two dissimilar networks.
    • Use Dial Plan – Select this checkbox to configure VTALL for use with your telephone system dialing plan.
    • IP Address to use for the Realtime Stream – Type your computer’s IP address for the VOIP connection.
    • Generate in band DTMF – Select this check box to make Virtual Terminal emulate and transmit DTMF
      (touch tone digit sounds) audibly over the audio path. (Not Recommended)
    • Use DNS to resolve a call destination when not operating in gatekeeper mode – Select this checkbox to find a call destination by it’s associated domain name instead of its IP address. This setting is not recommended because it can tie up Virtual Terminal operation while DNS tries to translate the domain name to its corresponding IP address.

  4. Click OK to save and close the Calling Options tab or Apply to save your changes .
