Hello Team,I am not sure this is the right place for this query. I have a Airtel Broad band connection who supplied Beetel Caller Id Phone (Model No M60).As I am using this phone for many Conference calls, I want to know how to keep a call in "Mute".Unfortunately this phone do not have a "Mute" Button.As per the phone features list it says "Taggle Mute".Can any one help me?Thanks in advance.With regards,Srinath
