Whats your say on this one?
i dont know what you want to ask. those are two quite different things. one just tells who called, one leaves a message, like a speaking SMS
I'd prefer voicemail as one can always leave their voice message if the call is not being attended, while missed call alert i guess is useless, coz even if u don't have this alert facility and u don't attend the call, your mobile phone does have the option of showing missed calls.
Voicemail if a bugger's constantly calling you (since they are charged for the call).
MCA if you don't want to go through the hassle of checking your voice mail (and paying for the calls)
Shaheerk........ you mean to say .......... both facilities are Ghatay ka Soda..... hehehehe
