Syntax
isdn ignore connect-ack [ incoming | outgoing ]
undo isdn ignore connect-ack [ incoming | outgoing ]
Default
After sending a CONNECT request, ISDN waits for a CONNECT ACK before it changes to the ACTIVE
state for traffic transmission.
After receiving a CONNECT request, ISDN sends a CONNECT ACK and changes to the ACTIVE state.
Views
ISDN interface view
Predefined user roles

Parameters
incoming: Specifies the incoming CONNECT ACK.
outgoing: Specifies the outgoing CONNECT ACK.
Usage guidelines
The setting for this command must be consistent with the setting on the service provider switch.
• If the service provider switch does not send CONNECT ACK, configure the isdn ignore connect-ack
incoming command. After sending a CONNECT message, ISDN changes to the ACTIVE state
without waiting for an acknowledgement.
• If the service provider switch does not receive CONNECT ACK, configure the isdn ignore
connect-ack outgoing command. After receiving a CONNECT message, ISDN changes to the
ACTIVE state without sending an acknowledgement.
You can configure this command only when no calls are present on the ISDN interface.
