Use the System - Media window to specify the amount of bandwidth to reserve, across all physical interfaces, for non-RTP media. The value is specified as a percentage and applies to the system as a whole. The range allowed is 0 to 50, with the default value of 0. This value applies only to TCP media traffic such as MSRP. Refer to MSRP Support for more information.

Use the Enhanced Application Media Support flag for the following functionality:

  • The SBC initiates and establishes TCP on the egress leg only after the TCP connection is successful on ingress leg.
  • The SBC supports transmitting URG (urgent) data from one leg to another.
  • The SBC supports establishing and disconnecting a TCP connection multiple times within the same SIP session.

On the SBC main screen, go to All > System > Media. The Media window opens.

The following options appear:

ParameterDescription
Dedicated BW For Non RTPMediaSpecify (reserve) an amount, as a percentage, of bandwidth usage to limit across all physical interfaces for non-RTP media.
Enhanced Application Media SupportUse this flag to establish/disconnect a Application media TCP session by:
  • using a SIP device (not the SBC itself) to trigger the establishment of an application media TCP connection, and
  • disconnect and re-establish application media TCP connection without disconnecting the SIP session.

The default value is Disabled. 

Note

Configure Dedicated BW For Non RTPMedia to a non-zero value to reserve a percentage of NIF bandwidth for non-RTP calls.

Make the required changes and click Save at the right hand bottom of the panel to save the changes made.
