No voice from other side in first attempt for most calls on BSNL

Hi,

Ok, my father has bsnl mobile, now a days what I am noticing that whenever he receives or make a call, on first attempt mostly there is no sound from other side.
Earlier I think its handset problem but I don't think it is so because in second attempt, it works..

Anyone else facing same problem on bsnl mobile network ?

I think BSNL is never going to be a good service. Today from last 3 hours , the out going is not working !
