anup tuladhar...please explain what ringing conditions..like you want you controller to detect there rings then answer the call automatically or what please expalin i will provide some sort of help.
one more thing;
y the most of the people except (Michael) try to disturb the user who is asking a question...like you have no idea how how the user needs help...i think the administrator should ban those people who provide suggestions instead act like James Bond...

like for e.g.

"I was interested in how long Anup had to implement his project. If he graduates next year, he will be busy but should have no problem getting this done.
Graduating in two months, I don't know, seems like a LOT to do in a very short time...where EVERYTHING is new.
Dennis "

what hell this has to do with the question..just help him or don't reply..r u going to get some kind of asker_award after finding who he is and why he is asking the question..
