Sounds like a firewall or ACL.
while offhook, press the "?" 2 x, see if there the phone is sending packets or go to the network settings and get the IP Address.
You could try to reset the phone to factory.

The Cisco 7940 Phone...if you work from home and use this phone can your Corp office be able to monitor your calls?

It is possible for them to monitor voip calls, if your call passes through their network, or they do remote monitoring on network traffic. The voip traffic is only data that needs to be 'reassembled' to hear the voice stream. However, this is more difficult if the traffic is encrypted between the phone and the call manager or whatever they are using.

I am no legal person, but I am sure that you would have to have agreed to have your calls monitored for them to be able to do this.

My red light wont go out on cisco 7940 phone, even when i have no messages


Has this just stopped working, or has it never been working?

On the call manager / CME the MWI (Message Waiting Indicator) needs to be configured. This could be undertaken either via the GUI or from the CLI

For instance ...

ephone-dn 30
number 8000...
mwi on
ephone-dn 31
number 8001...
mwi off

and also mapped to each phone to enable MWI status

ephone-dn 1 dual-line
number 111
label Chris
name fred
call-forward busy 800
call-forward noan 800 timeout 10
huntstop channel
mwi-type visual

Complete config details are at:

You probably have the speaker membrane broken. Just plug a headphone and test to see if the rest of the device is working correctly.
