Do you have a maintenance contract and do you need 15x features?

So your maintenance contract doesn't support changing IOS versions? (That's far different opening a TAC case.)

Hello, Stefanio38.
Is there any difference at the configuration between this problem ports and ports that works well? Does another devices works well at this ports? Is there any errors at this ports?
Best Regards.

Hi,
Both your Gi3/0/21 and Gi3/0/24 ports have hardcoded speed and duplex. Can you please configure both to "auto" and see if there is any progress.
Best regards,
Antonin

Hi.
Is there any errors by commands "show interface Gi3/0/21" and "show interface Gi3/0/24"?
Best Regards.

Hi, Allert,

Well, the last test that I can to offer is to put another device (not a phone) to this port and look how good it works. If there is problems as well than there could be damaged ports. If not than it's better to contact TAC if you (or your client) has a SmartNet contract.
Best Regards.

Could it be not a switch problem? For example could it be out of license or extension numbers at the phone server side?
Best Regards.
