Check if the port or switch the phone is connected to is down. Also, eliminate any DNS or other connectivity errors.
How to fix a Cisco 7965G that does not go through its normal startup process?
If your Cisco Unified IP Phone isn't starting up normally, the issue could stem from faulty cables, bad connections, network outages, or a lack of power. Begin by verifying that the network port is functional and that the phone is receiving power. If problems persist, try powering up the phone with the handset off-hook. As a last resort, perform a factory reset of the phone.

If your Cisco Unified IP Phone can't obtain an IP address, ensure that the network or VLAN the phone is connected to has access to the DHCP server. Also, confirm that the switch port is enabled.

If you are disconnected from a call joined via Barge on your Cisco IP Phone, it's likely because the call was put on hold, transferred, or turned into a conference call.

Barge may fail on your Cisco IP Phone, resulting in a fast busy tone, if the phone you are using is not configured for encryption while attempting to barge an encrypted call.
What to do after factory reset deleted 802.1X shared secret on Cisco IP Phone?

If Barge fails on your Cisco IP Phone and you hear a fast busy tone, it's because you cannot barge an encrypted call if your phone is not configured for encryption.

If you cannot hear a dial tone or complete a call on your Cisco IP Phone, it might be because you need to log into the Extension Mobility service. Alternatively, if you are using an SCCP phone, you might need to enter a client matter code (CMC) or forced authorization code (FAC) after dialing a number. Also, your phone might have time-of-day restrictions that prevent you from using some features during certain hours.
