Parameter incoming: Ignores the Sending Complete Information Element in Setup messages
when receiving a call.
outgoing: Sends Setup messages without the Sending Complete Information
Element when placing a call.
Description Use the
isdn ignore sending-complete command to configure the ISDN
protocol to ignore the Sending Complete Information Element in Setup messages
when receiving a call, or to send Setup messages without the Sending Complete
Information Element when placing a call.
Use the
undo isdn ignore sending-complete command to restore the default
setting.
As for the data exchange performed between a router and an ISDN switch, the
default is as follows.
■ For an incoming call, the router 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.
If you execute the isdn ignore sending-complete command with no keyword
specified, the Sending Complete Information Element-related operations are
performed when a router receives a call or places a call.

■ In the event that the router is communicating with an ISDN exchange, its
settings must be the same as those on the exchange.
■ Only with DSS1, QSIG or ETSI on interface ISDN protocol can this command be
configured.
You are not allowed to configure this command on an ISDN interface if there is still
a call on it. This command can take effect only if it is configured when there is no
call on the interface. Alternatively, you can manually disable the interface by
