Before You Upgrade
When upgrading 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.
Upgrade Rule Workaround
If you are upgrading using an upgrade rule, the following example can be used to upgrade successfully:
where “lt” means “less than” and the command is entered in a single line. For more information on the upgrade rule, including a syntax description, see the Upgrade Rule section in the Cisco Small Business IP Telephony Devices Provisioning Guide, Chapter 2, beginning on page 44.
Behavior During Times of Network Congestion
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:
- Administrative tasks, such as an internal port scan or security scan
- Attacks that occur on your network, such as a Denial of Service attack
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.
