Phone Firmware

The recommended phone firmware is dependent upon the version of CME or CUCM you are attempting to connect to. The tables below indicate the suggested phone firmware versions and filenames for the various CME and CUCM versions we use in the labs. Note that sometimes you need to "step up" to the suggested firmware version by loading some number of intermediate firmwares. These step up procedures can be difficult to find information on and so common ones have been documented below.

When configuring CME for the firmware for use with each device the load command should use the file indicated by the asterisk (*) in each list of files.

  • .cop.sgn files can be loaded into CUCM through the OS Admin > Software Upgrades menu. Each device model has a default load specified in the Device > Device Settings > Device Defaults page of CUCM unless it is overridden by a "Phone Load Name" on the configuration page for a specific device.

SCCP Firmware Step Up Procedures by Model

7940/7960

If your phone currently has firmware older than SCCP v8.0(10):

You must upgrade to 8.1(1) before upgrading any further.

Note: With these models if you are going to/from various SIP or MGCP firmware versions additional intermediate firmware files may be required.

7941/7961

If your phone currently has firmware older than SCCP v6.0(2):

You must upgrade to 7.0(x) before upgrading any further. Cisco suggests upgrading to 7.0(3) as that will provide a faster upgrade to 8.x(x) than an older 7.0(x) would but any 7.0(x) will work. Once you have 7.0(3) loaded skip down to the section for phones with 7.0(3) below.

If your phone currently has firmware between 6.0(2) and 7.0(2):

You can upgrade directly to 8.5(2) but be aware that the upgrade will take about twice as long as usual.

If your phone currently has firmware between 7.0(3) and 8.3(2):

Cisco changed the signing certificate on the firmware, before you can load newer versions you need to upgrade your phone to at least 8.3(3) but it is suggested that you upgrade to 8.5(2). Once you have something between 8.3(3) and 8.5(2) loaded you will be able to continue upgrading to the latest version.

7942/7962

If your phone currently has firmware older than SCCP v6.0(2):

You must upgrade to 7.0(x) before upgrading any further. Cisco suggests upgrading to 7.0(3) as that will provide a faster upgrade to 8.x(x) than an older 7.0(x) would but any 7.0(x) will work. Once you have 7.0(3) loaded skip down to the section for phones with 7.0(3) below.

If your phone currently has firmware between 6.0(2) and 7.0(2):

You can upgrade directly to 8.5(2) but be aware that the upgrade will take about twice as long as usual.

If your phone currently has firmware between 7.0(3) and 8.3(2):

Once you have something between 8.3(3) and 8.5(2) loaded you will be able to continue upgrading to the latest version.
