19 Appendix H: PictureCallerID (6867i/6739i)
19.1 Introduction
This feature, unique to the Aastra 6739i, allows the display of a picture referenced by the Caller ID
number for an incoming and an outgoing call.
When the user makes or receives a call, the Aastra 6739i (by configuration) fetches an image
stored on a TFTP/FTP/HTTP/HTTPS server and displays it.
For instance, if the incoming or outgoing number is “9725551234” the phone makes a request for a
file named “9725551234.png” which must be
6739i
 150x200 pixels
 png format
 24 bits depth colors
6867i
 Up to 150x200 pixels (image is rescaled)
 png format
 24 or 32 bits depth colors
in order to be displayed. The image is cached in the phone until the next reboot.
If no image matching the request is found on the server or in its cache, the phone displays a default
image (below).
