Configure Subscriber Gateway

This step is mandatory.

Enter the following information.


Parameter

Description
Use static NAT mapping Specifies whether the NE should perform Network Address Translation on the contents of messages sent to this Subscriber Gateway. Values:
  • True
    Select this value if the Subscriber Gateway is on a separate IP network from the NE and there is no Session Border Controller to provide the translation.
  • False
    Select this value if the Subscriber Gateway is on the same IP network as the NE, or if they are on separate networks and there is a Session Border Controller associated with the firewall between the networks.
Maximum concurrent media streams allowed Maximum number of bi-directional RTP media streams (RTP terminations) that can exist concurrently on this gateway. A value of zero (the default) indicates no limit. Changing this value changes the maximum IP bandwidth that may be taken up by calls associated with this gateway.
Maximum concurrent high bandwidth media streams allowed Maximum number of high bandwidth bi-directional RTP media streams (RTP terminations) that can exist concurrently on this gateway. This value must not exceed Maximum concurrent media streams allowed, unless that value is zero. A value of zero (the default) indicates that the number of streams is limited only by Maximum concurrent media streams allowed. Changing this value changes the maximum IP bandwidth that may be taken up by calls associated with this gateway.
