I am having a weired issue with one cisco 8851 phone. It has a few lines and its got a headset connected via aux port and a bluetooth mobile (samsung) paired as well. The phone started lagging recently. When the user clicks on new call it takes a few seconds for the new call screen to come up. Sometimes about 10 seconds. When the person hangs up the call it takes about the same time. overall the UI is very slow. When i reboot the phone it fixes the problem but it starts happening in a few days. I cant find anything online about this issue.
Thank you,
Usman.
