Usage guidelines
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 an outgoing call, 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 switch, its settings must be the same as those
on the switch.
Configure this command on an interface only when the ISDN protocol running on the interface is DSS1,
Q.SIG, or ETSI.
