RE: T22P Speaker Muted after Firmware Upgrade?
Hi,

Do you mean that when there is an incoming call, you can see the call info in phone LCD but speaker doesn't ring?

Can you try these steps in a phone with V73:
1. Disconnect network cable.
2. Reset phone by Menu-> Setting-> Advanced setting-> Reset.
3. After rebooting, try the speaker button.

Note: Network cable can't be connected to phone in the whole process.

Regards,
James
