This problem only occurs in one department at my organization. The department has 5 IP phones (7960).
The first issue is that there is so much static during calls that they cannot hear the caller clearly.
The second issue is that they cannot answer a call. They pick up the handset but the call isn't answered, the phone keeps ringing. Then they press the button for the line that is ringing but the call is still not answered. Eventually the call goes to voice mail or the caller hangs up. Also, the phone seem to lock up during a call and the light on the handset starts to flash. Eventually the call is lost.
Both these problems occur at random times. There's no pattern. It's been happening for about five days now.
The only thing in common among the phones is that they are located in the same office and all have one extension in common (although each phone has other extensions on it).
The issues only seem to occur with incoming calls. And these calls seem to always be from outside the organization.
Help!
