Skype,how to make someone see my video call?

[Sameer]

wen i make a video call to a client,i wanna show that video call to my boss as well,i cant make a conference as the client wont permit me for a conference call.my id and password is with my boss.but how to make it possible while hiding it from the client.
yeah the client is in a different city,and call is gonna happen at non office hours,boss is actually testing me or monitoring how i deal with customers.we dont wanna share with the client our company training ways.as we keep in totally confidential i cant record the call or so.
