Cant resume on hold calls in cucm 9.1
I am a telecom/network administrator for a bank. Lately I have been having users complaining that often when they put a user on hold to either check on something or to transfer them, they cant resume the call. They hit the resume button but the phone does not respond. This is happening on at least 5 phone in the same branch. Please let me know if I can provide any further information.

I am going to upgrade the firmware hopefully today and will comment back. I welcome any other comments or suggestions.
You can always try unplugging the headset piece and do a conference to see if it matches the bug conditions.

They use headsets at this location. In order to update firmware on just a couple of phone, do I need to load the new firmware in cucm and then just reset the two phones or is there an easier way to just update 2 phones?
This guide explains how to upgrade the firmware on just 1 or 2 phones, disregard the topic about the Auth Fail error

My earlier post was wrong. I meant to say they don't use headsets at this location. Just wanted to clarify that.
