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.
