[cisco-voip] Beep for no reason?

Tue Oct 4 13:35:59 EDT 2005

Sounds like you are running into this:
CSCef09922 - CallManager relays DTMF tones to phone from held device
Symptoms:

DTMF tones are heard on an IP Phone when the phone has a call on hold 
and is
either idle or on the phone with another call.

Conditions:

When a phone places a caller on hold, if the held party presses DTMF 
digits, the
holding party will hear them even if they are on another call.

Workaround:

None.

This is a duplicate of  CSCec72433.  For 4.0(2a) it is fixed in ES33.  
I believe someone else mentioned they were using 4.1(2).  This is fixed 
in 4.1(2)es26.  For either case you will need to open a TAC case to get 
the ES with the fix or the latest ES which will also contain the fix.  
The fix looks to be incorporated into the base version of 4.1(3).

HTH,
Kevin
