Check the PC Port setting from the phone and verify that it is not disabled.

Login to Switch, check on what vlan the phone mac has been learnt on.

use the show mac address-table

Check column 1.

What is the phone model ? We've had similar issues, usually unplugging/ plugging works.

Check phone IP . Usually it takes IP from the voice vlan,

But at times, it does take the IP from the data vlan & now the pc doesn't have a source from which it can request

( Sorry, technically not so strong to explain)

Thanks for your sugestions..i resolved the issue..
