20 For any IP Phones that did not upgrade successfully, try one of the
following (in order):
• use the isetReset ''IP Address'' command
• enter the following combination of keystrokes on the IP Phone:
release, mute, up, down, up, down, up, mute, 9, release
• power the IP Phone off and then on again
If the upgrade was unsuccessful on any of the IP Phones, this is probably
due to one of the following reasons:
• one of the Voice Gateway Media Cards did not upgrade the software
successfully
• an IP Phone is loaded with a firmware version that was unable to be
upgraded by the Voice Gateway Media Card in the normal manner
•the umsUpgradeAll command was not issued
• one of the cards has not been reset
If the upgrade was unsuccessful, re-do the appropriate procedure. If
the upgrade is still unsuccessful, contact the technical support
representative for further assistance.
