Hi, we are a data security company and we have an interesting challenge in
the mobile world: We would like to send a security code that will appear
simultaneously on the incoming call screen of the receiver's phone before he
answers the call. On top of that, we would like to send an additional
security code during the conversation, and we would like it to appear on the
receiver's phone screen (next/under the call ID and call duration) in real
time. Any ideas?
