ISUP Local Signaling Destination

The ISUP Local Signaling Destination object is a child of the Call Agent.

The ISUP Local Signaling Destination object contains configuration parameters and status information for the ISUP signaling stack in the MetaSwitch VP3000. There is only a single ISUP Local Signaling Destination object, which is created before delivery of MetaSwitch VP3000 and you cannot destroy.

To start the ISUP Local Signaling Destination, you need to do the following:

Parameter

Access

Description
ISUP Local Signaling Destination index Read only The EMS's identifier for this ISUP Local Signaling Destination object. This is used to identify the object when using the EMS's configuration export / import function.
Pass on message Change Inactive Specifies whether a message which was not fully understood should be forwarded. Values:
  • True (default)
  • False
Congestion status Read only Congestion level of the exchange. Values:
  • Level 1
  • Level 2
  • Level 3
  • Uncongested
CLLI Change Inactive This field is not valid in the UK.
Suppress echo cancellation requests Change Inactive Specifies whether echo cancellation requests in outgoing IAMs are to be suppressed (in which case the VP3000 itself performs any echo cancellation required). This option is used to avoid requesting echo cancellation resources in networks where such resources are scarce. Note that, in contrast to local or regional calls where echo cancellation is unlikely to be used, echo cancellation is almost always used in VoDSL calls to deal with packetisation delay. This can be problematic in networks which are not provisioned to have additional echo cancellation resources. Values:
  • True
  • False (default)
