These Release Notes describe the updates and fixes in version 7.6.1 of the Cisco Small Business SPA30X, SPA50X, and SPA51X IP Phone firmware.
As with any firmware release, read these release notes before you upgrade the firmware. Cisco also recommends that you back up the configuration before you perform any firmware upgrade.
When you upgrade a Cisco SPA50X or Cisco SPA30X IP Phone, if you have installed a firmware version prior to 7.5.2b, you must first upgrade to 7.5.2b before you upgrade to release 7.5.3 or to a later release. See the following table for more information.
For SPA30X, SPA50X, and SPA51X, the openssl upgrades from openssl 0.9.8zc to openssl 0.9.8zg.
SUBSCRIBE failover behavior is the same as the behavior of Register/Invite messages. The phone restarts subscribe messages, including subscribe event type Call-Info, BLF, Hoteling, and as-feature-event, if the registration IP changes, regardless of the Auto Register When Failover setting.
When the Auto Register When Failover setting is Yes, all SUBSCRIBE failovers trigger reregistration.
Anything that degrades network performance can affect voice and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:
To reduce or eliminate any adverse effects to the devices, schedule administrative network tasks during a time when the devices are not being used or exclude the devices from testing.
