Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses issues that are classified as priority
level 1 or priority level 2; these classifications are assigned when severe network
degradation significantly impacts business operations. When you contact the TAC
Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will
automatically open a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country,

Before calling, please check with your network operations center to determine the
level of Cisco support services to which your company is entitled; for example,
SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In
addition, please have available your service agreement number and your product
serial number.
