ISDN interface view

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.

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.

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
