With dial up if one subs cribes to Call Waiting, when the call comes line is dropped.
To disable this feature one need to add some preceeding code to the number dialed so that during the life of that connection call waiting is disabled.
In some countires one need to add *70+ISP nuber to render call witing off during the length of that call.
Could you please find what we need to do in Pakistan?
