ISDN BRI interface view, CE1/PRI interface view, CT1/PRI interface view
Parameter

Description
Using the isdn ignore callednum command, the user can disable the SETUP ACK
messages if the received SETUP messages in data service calls do not carry the
called number information.. Using undo isdn ignore callednum command, the
router will send SETUP ACK messages.
By default, the router that is interoperating with an exchange sends SETUP ACK
messages even if the received SETUP messages do not carry the called number
information.
The switches of some vendors neither carry the called number information in the
SETUP messages nor recognize SETUP ACK messages. In this case, a router must
be disabled to send SETUP ACK messages by using this command when
interoperating with the switches of such vendors.
With CE1/PRI or CT1/PRI interfaces, you must configure PRI bundling before you
can configure this command in serial interface view. For more information about PRI
bundling, refer to the commands pri-set (CE1/PRI Interface) and pri-set (CT1/PRI
Interface).
