As its my work place i make the rules which is good and bad, and let's face it - for most of the younger generation its all texting anyway. For me i do have more than one as i run more than one business but it's the same rule for all of them. They will only ever get answered between 9 and 5 unless its friends or an important call which for the most part doesnt happen too often.
If i am with someone or otherwise engaging with someone for work purposes it never gets answered at all and is on silent. I think its very rude to do it and i want all of your attention if youre talking to me and i would hope you would do the same. In my office or others, if im working, it is not on silent but it is an "old phone" ring tone and it is on the first volume adjustment i.e. as low as it will possibly go as i cant always feel it and that way it doesnt intrude on anyones personal space. I always go out of the room and genreally out of the area that im in to answer it. If it rings i instantly put it on silent (press the volume button)If its on my desk it doesnt really matter as im the only one home and its sitting on its cradle and easy to see.
