View

ISDN interface view

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-completecommand 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-completecommand 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-completecommand with no keyword

 

specified, the Sending Complete Information Element-related operations are

 

performed when a router receives a call or places a call.

n

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
