I am considering an application (dialplan?) that needs to write interactive messages for workflow to the display on the phone. This would be text that is content, not menu selections. Kind of a Call Center app without the screen pops.
Is there a pattern already in Asterisk for this kind of interactive text display?
Do the IP Phones have well-known functions that accept text for display?
Or do you have to have a volume OEM agreement with a phone manufacturer before they take an interest in showing you that part of their support knowledgebase?
I like the WiFi phones like the F100G and maybe better is the Linksys portable IP Phone which seems to have a web-type display.
