My views are little different.
My clients, current or prospective also reject the call. But then what is there to get dejected about? When I conduct the training, I also do the same thing! Attending the meetings and conferences or some important work is order of the day. It is not possible to take every call right at that moment, neither do I expect so from other party.
However, what is against business etiquettes is not to call back or send SMS expressing your inability to take the call.
There is provision for auto response through SMS also. However, it could be costly solution depending on the tariffs of the mobile service provider.
The No 1 trouble in India is our incoming calls are not chargeable. Earlier incoming calls on the mobile were chargeable but not after 2003. TRAI has removed charges on incoming calls in this year and we the garrulous Indians have become further garrulous. Imagine TRAI gives option or authority to Telecom companies to levy charges on incoming calls. Then will you have the same opinion or even grudge for rejecting the call?
I had not been to USA but then those who had been there told me that since incoming calls are chargeable, no American prefer taking call if it is from unknown caller. For unknown callers, the call goes to the voice mail.
I recommend you keeping a log and finding out how many calls were for worthwhile reasons. If you are senior person then tell your subordinates to maintain similar log. Take a feedback from them and find out how many calls had a real purpose and how many were for frivolous reasons. I am confident that latter will get primacy over former.

Beware of false knowledge; it is more dangerous than ignorance.
In my article, I have already explained the solution and it doesn't take much time also. Whenever someone doesn't wish to take calls, s/he only has to activate call filtering program on his mobile. Calls will keep coming but phone wouldn't ring. Later, looking at the missed call, one may decide whom to call back.
When, a better way of handling an issue is available, that too free of cost, isn't it wiser to implement it. After all, we, in corporate world, talk so much about following the best practices. It's my personal opinion and I may be wrong; just sharing my thoughts.
