[Linphone-users] Feature suggestion: Show image (or video stream) from an HTTP source on incoming call

[Daniel Schausberger]

This feature would be very useful for SIP doorbells.

If someone pushes the button on the doorbell, Linphone could show the camera 
image (or maybe optional, an RTSP video stream) as the contact person's icon 
_before_ the call is answered.

SIP protocol already seems to offer a header option for it, but this is not 
used in any Android SIP client at the moment...
("Call-Info: <http://asdf/image.jpg> \;purpose=icon")

Anyway, it would also be a great alternative if you could set a static HTTP 
image link to be displayed in the client on an incoming call.

Thank you
