For the past week, 2 of our sites have been experancing a rather odd issue. The issue is, that on two phones at each location, while on a call, if another call comes in for that line or for another line on the phone, the little beep sound is not heard when the second call comes in. This is not happening for any other phones on the call manager. I have tested with other phones and when calling them while on a call, the beep sound can be heard on the phone when the second call comes in.
This has only been happening for around a week or so.
We haven't upgraded the OS, CCM, phone software or made any other changes.
The only thing that had happened at both locations was the call managers had been rebooted.
I was just wondering if anyone would know how to enable the beep sound again for when a second call comes in on these phones.
The Call Manager version running at both sites is: v3.3.3
The phones that have had the issue are all 7960's
Tonight i have tested with upgrading the firmware on the 7940/7960 phones, however this still didn't make a differance.
Would anyone have any suggestions?
