  • dryup (default)
  • force
  • undefined
cac 

Call admission control parameters for this H.323 trunk group. Specify the following CAC parameters:

  • bandwidthLimit – Total media bandwidth limit (in K bits/sec). (range: 0-2147483647, or unlimited / default is ‘unlimited’).
  • bandwidthLimitThreshold – Bandwidth limit notification threshold, as a percentage. (range: 0-100 / default = 0)
  • callLimit – Total number of either ingress or egress concurrent calls allowed. (range: 0-2147483647, or unlimited).
  • callLimitThreshold – Call limit notification threshold, as a percentage. (range: 0-100 / default = 0)

  • silc – The SILC traffic control configuration.
    • MC1Percent – Percentage of calls to accept when the machine congestion level is 1. (range: 0-100 / default = 75).
    • MC2Percent – Percentage of calls to accept when the machine congestion level is 2. (range: 0-100 / default = 25).

If the timeout period expires, the answer supervision action specified is triggered. A value of "0" disables this timer (range: 0-1000 / default = 300).

    • enabled
dryUpTimeout  Timeout value (in minutes) for the dry up action. (range: 1-1440 / default = 5).
ingressIpPrefixIngress peers matching these ingress IP prefixes are assigned to this H.323 trunk group. Up to 128 ingressIpPrefix entries may be assigned to a H.323 trunk group. Enter IPv4 or IPv6 address in the following format:
  • <IPv4 or IPv6 address> – The V4 IP address is in dotted decimal form (for example, 128.127.50.224).  The V6 IP address is in hexadecimal/colon form (for example, 1280:1276:3350:2224:2222:3333:8888:1245 or ffd00:21:445:128::7880). (default is 0:0:0:0:0:0:0:0).
  • <prefixLength> – The number of bits of address which form the network part of the IPv6 address. Rest of the bits (128 – prefix length) specify the host part of the IPv6 address. Must be 0-128.
mediaSpecifies the parameters associated with media features for this H.323 trunk group. Specify the following media parameters: 
  • directMediaAllowed– Enable flag to set up a direct-media path so that media flows directly between endpoints in the same direct-media group.

    • enabled
  • directMediaGroupId – Direct media group to which this trunk group belongs. (range: 0-65535 / default = 0).
  • mediaIpAddress – The IPv4 media IP address assigned to this H.323 trunk group. Any IP address configured must belong to the ipInterfaceGroup configured as the mediaIpInterfaceGroup for the trunk group (default = 0.0.0.0).
  • mediaIpInterfaceGroupName – Specifies the interface group to be used for media.
  • mediaPortRange – 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.

When provisioning a UDP media port range, set the range slightly larger than the actual number of ports needed to support maximum simultaneous calls.

  • preAllocateResPad– This indicates if a resource pad is pre-allocated or not during an incoming fast start call procedure that results in G.711 codec selected for the call.
    • disabled (default)
    • enabled
  • slowStart– Use this flag to determine whether an ingress H.245 Slow Start is converted to a forward offer (Fast Start) at egress, or passed through as a reverse offer (Slow Start).

    • passthru

      Because video is only supported for H.323-H.323 Slow Start calls, use passthru option in this scenario.
