Hi
I have a strange issue with Access switch & Cisco 6941 phone.
On the switch site I am using cisco 4506 as a access switch & Phone type is 6941.
The access port on the switch is had coded to 100Mbps Full duplex & Phone is on the default configuration.
This is the access switch config
sh run int GigabitEthernet3/7
Building configuration...
interface GigabitEthernet3/7

Try to change the duplex value to half on the switch interface gi3/7.
And let us know the status
