This section describes how to install firmware release 8.2(1) for SCCP.

Firmware Upgrade Issues for SCCP

Note the following firmware upgrade issues:

•If you are currently running firmware earlier than 6.0(2) on a Cisco Unified IP Phone 7906G and 7911G and want to upgrade to 8.0(x), you must first install an intervening 7.0(x) load to prevent upgrade failure. Cisco recommends using the most recent 7.0(3) load as the intervening load to avoid lengthy upgrade times.

•If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone 7906G and 7911G and want to upgrade to 8.0(x), you can do so directly. However, expect the upgrade to take twice as long as usual.

Firmware Installation Procedure for SCCP

Before using the Cisco Unified IP Phone 7906G and 7911G with Cisco Unified CallManager release 3.3 or later, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster.

Important Notes

This section contains these topics:

•Failover Time Using TCP is Faster than Failover Time with UDP (SIP Only)

•How a Cisco Unified IP Phone Determines the TFTP Server Address

•How a Cisco Unified IP Phone Determines the TFTP Server Address

Failover Time Using TCP is Faster than Failover Time with UDP (SIP Only)

You can configure SIP profiles for the Cisco Unified IP Phone 7906G and 7911G to operate with Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) by using the SIP Phone Security Profile Configuration window in Cisco Unified CallManager Administration.

If you select TCP as a transport protocol, the failover time between primary, secondary, and tertiary Cisco Unified CallManagers is approximately 5 seconds or less. If you select UDP, the failover time is approximately 120 seconds. The TCP phone recovers faster since it detects the TCP link failure faster (less than 5 seconds) where the UDP phone depends on SIP KeepAlive entirely; this can take up to 120 seconds. This scenario applies to a Cisco Unified CallManager "clean" shutdown.

In the case of a Cisco Unified CallManager crash or a router crash, the failover time for a TCP phone and a UDP phone are about the same. In this case, both the TCP and UDP phones rely on SIP KeepAlive to detect the link failure.

How a Cisco Unified IP Phone Determines the TFTP Server Address

A Cisco Unified IP Phone (firmware release 8.0(4) and later) follows an order of precedence for selecting the TFTP server address if the phone receives conflicting information from the DHCP server. For complete information on how the phone selects its TFTP server address, see the "Cisco TFTP" chapter of the Cisco Unified CallManager New and Changed Information Guide, Release 5.1(1).

Cisco Product Security Overview

Cisco provides a free online Security Vulnerability Policy portal at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you will find information about how to:

•Report security vulnerabilities in Cisco products.

•Obtain assistance with security incidents that involve Cisco products.

•Register to receive security information from Cisco.

A current list of security advisories, security notices, and security responses for Cisco products is available at this URL:

http://www.cisco.com/go/psirt

To see security advisories, security notices, and security responses as they are updated in real time, you can subscribe to the Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed. Information about how to subscribe to the PSIRT RSS feed is found at this URL:

http://www.cisco.com/en/US/products/products_psirt_rss_feed.html

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

•For Emergencies only — security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

•For Nonemergencies — psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

•1 877 228-7302

•1 408 525-6532

---

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
