A VoIP phone is plugged into a port but cannot receive calls. Which of the following needs to be done on the port to address the issue?

Trunking all VLANs on the port may not be necessary if the VoIP phone only requires access to a specific voice VLAN. Trunking allows multiple VLANs to be carried over a single connection, but it does not directly address the need for the VoIP phone to receive calls, which is dependent on proper tagging to the correct VLAN.

Configuring the native VLAN is important for untagged traffic but does not solve the issue of a VoIP phone not receiving calls. The native VLAN typically handles untagged frames, and while it may play a role in VLAN configuration, it does not ensure that the VoIP traffic is appropriately prioritized or tagged for voice communication.

Disabling the VLANs on the port would prevent any traffic from being sent or received, including voice traffic, leading to further issues rather than resolving the problem. This action would make the VoIP phone completely non-functional on the network.
