Use this object to define the parameters associated with the Media features for the specified gateway trunk group.

Note

As a best practice, always use UPPERCASE for trunk group names.

Command Parameters

Gateway Trunk Group Media Parameters

ParameterLength/RangeDescription
directMediaAllowedN/A

If enabled, attempt to set up a direct-media path so that media flows directly between endpoints in the same direct-media group.

  • disabled (default) 
  • enabled
mediaIpAddressIPv4/IPv6

Each trunk group can have a mediaIpAddress configured to specify a specific IP address to use when allocating UDP or TCP media. Default is "0.0.0.0".

The mediaIpAddress can be configured as either an IPv4 of IPv6 address (except for H.323 which does not support IPv6 addresses). Any IP address configured must belong to the ipInterfaceGroup configured as the mediaIpInterfaceGroupName for the trunk group.

NOTE: If you prefer to instead choose an IP Address from a range of values configured in mediaPortRange (UDP) or tcpPortRange, use the default value “0.0.0.0” for mediaIpAddress parameter.

mediaIpInterfaceGroupNameN/AName of the IP interface group for media.
mediaPortRangeN/A

Use this media control to set the baseUdpPort and maxUdpPort RTP/RTCP ranges for the specified SIP trunk group.

  • baseUdpPort – The starting (base) port number for the range of UDP ports to use for RTP/RTCP media (inclusive). This value must be within the system-wide media port range. The baseUdpPort range is 1024-65534, or "none" (the default value which indicates SBC does not apply this SIP trunk group control, and instead uses the mediaPortRange specified by system-wide settings).
  • maxUdpPort – The maximum UDP port number for the range of UDP ports to use for RTP/RTCP media (inclusive). This value must be greater than the baseUdpPort and within the system-wide media port range. The maxUdpPort range is 1024-65534, or "none" (the default value which indicates SBC does not apply this SIP trunk group control, and instead uses the mediaPortRange specified by system-wide settings.

 

sourceAddressFiltering N/A

When enabled, incoming media packets which do not match the expected source IP address and UDP port are filtered out.
