You cannot use the calling card option.Only way you can use is to manually configure the dialing no.I have done it earlier.Just add "," for the waiting time.You have to find the correct format by trial and error.The regular method of using the it card is like,calling 160244 after some time u dial the secret no..the system asks u for confirmation..tells u the balance...then dial the no..so on...I don't know the actual procedure..since i don't use it..So what u have to do is add commas in place of the messages and nos for the input...for example,ur dialing no looks like this...160244,,,,,,,XXXXXXXXXXXXX,,,,,1,,,,172233.Sort it out using trial and error.The basic idea is to add commas before input..Post the feed backs..
