Item Description
Ignore the Sending-Complete
Information Element in Setup
Messages
•
Enable for outgoing direction—Configure the ISDN protocol to send Setup
messages without the Sending-Complete Information Element when
placing a call.
•
Enable for incoming direction—Configure the ISDN protocol to ignore the
Sending-Complete Information Element in Setup messages when receiving
a call.
•
Enable for bidirectional directions—Configure the ISDN protocol to ignore
the Sending-Complete Information Element in Setup messages when
receiving a call, and to send Setup messages without the
Sending-Complete Information Element when placing a call.
•
Disable (default)—Configure the ISDN not to ignore the Sending-Complete
Information Element in Setup messages. When the data exchange
performed between the device and an ISDN switch, for an incoming call,
the device checks the received Setup messages for the Sending-Complete
Information Element to determine whether or not the number is received
completely. If a Setup message does contain the Sending-Complete
Information Element, the number is not received completely. For outgoing
calls, a Setup message containing the Sending-Complete Information
Element indicates that the number is sent completely.
