I am having problems with a client, on a device model cisco 8821, it does not show the missed calls.
Firmware used on the device: sip8821.11-0-3ES13-5
There are other devices of the same model and this problem does not happen.
Solved! Go to Solution.

Thank you.

Two things to check:
On the DN configuration page for the DN on that phone, is the following box checked or unchecked?
On the phone's configuration page, is there anything in these fields?

Roger that. I was hoping your problem was that simple. I'm in agreement with the other folks that it is some weird interaction between firmware and possibly the wireless network. It's time to call TAC if you are able.

Please try to change the firmware on the phone to cmterm-8821-sip.11-0-4SR3-3.k3.cop.sgn
