Identification: Beautiful houseplant with orange flowers-

My friend has this beautiful orange flowering houseplant. I told her I would try to identify it. Anyone have any ideas? Thanks.

 

Looks like a lipstick vine. (Aeschynanthus pulcher) Their colors vary from red to orange.

 

Ditto to Aeschynanthus, it's not A. pulcher though. More like a cultivar with Aeschynanthus speciosus in its ancestry.

 

Thanks!
