  • Username – Supplied by the provider, this parameter is usually the phone number associated with the SIP account.
  • Auth Username – Supplied by the provider, this parameter is used for SIP digest authentication. It is not used if the provider employs IP address-based authentication.
  • Password – Supplied by the provider, this parameter is used with the Auth Username for SIP digest authentication. It is not used if the provider employs IP address-based authentication.
  • Registration – Some providers require registration. If yours does, check this option and select a registration time. Default is 3600 seconds (one hour).

    • Inbound Calls

    • Always sent
    • Always sent unless overridden
    • Never sent
  • Music On Hold – Specify the music on hold (MOH) scheme for outbound calls made through this gateway. This setting does not affect any incoming calls.
  • Restrict Codecs – Specify the audio codecs, and if applicable for your provider, video codecs, that are allowed on calls made to or from this gateway. G729 licenses are available. Contact Technical Support if you need additional information.
