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:

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:
|
Congestion status | Read only | Congestion level of the exchange. Values:
|
CLLI | Change Inactive | CLLITM: Common Language(C) Location ID. This is a string of 12 alphanumeric digits assigned by TelcordiaTM, specifying the exact location of the local exchange. The CLLI is used to provide diagnostics information in circuit validation tests. If you do not have a CLLI assigned, you can set this field to any 12-digit alphanumeric string. |
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.
