Configuring SPID parameters for static configuration
The SPID of the PBX is provided by a common carrier. You must configure the same SPID value for the B1
channel and B2 channel as that of the PBX.
When you configure this task, follow these guidelines:
• After you configure the local dialing number (LDN), the calling number configured in the isdn
calling command becomes invalid.
• You can execute this command only if no call exists on the BRI.
• You cannot execute this command during the SPID negotiation on the BRI.

with a PBX that runs the NI protocol but does not support the SPID negotiation.
