Upgrade options

Once the Voice Gateway Media Card software and IP Phone firmware has
been verified, there are three upgrade options:
1Upgrade the Voice Gateway Media Card software.
– In this case, perform Procedure 65 on page 512 only.
This is the most frequently-used option is used; however, verify if an IP
Phone firmware upgrade is also required.
2Upgrade both the Voice Gateway Media Card software and IP Phone
firmware.
– In this case, perform a combination of Procedure 65 on page 512 and
Procedure 67 on page 517.
Note: Do not restart the Voice Gateway Media Cards until the end of
Procedure 67, as restarting the cards restarts all the IP Phones.
3Upgrade the IP Phone firmware.
– In this case, perform Procedure 67 on page 517 only.
Note: In this case, restart all IP Phones instead of all Voice Gateway
Media Cards. To do this, select a single test IP Phone and reset the
firmware only on that test telephone before completing the procedure on
all IP Phones. If the upgrade works properly, use the umsUpgradeAll
command to complete the upgrade on all the IP Phones.
