Please note: this article describes the "classic" way of sending text messages to the idle screen. A more modern / recently implemented feature is not limited to idle screen and provides a lot more options like message queue and multiline and Icon support. Please do not miss to review this as well: Notifications via Infobox
Text messages (desktop messages) to the idle screen of a Snom deskphone, follow these steps:
Configure the folowing settings on the phone's web interface:
Support broken Registrar to "on" Filter Packets from Registrar to "off" Network identity (port): 5060 Clear Desktop Message on Cancel --> "off" -> message stays permanently --> "on" -> message can be deleted via "Cancel" key
Note: Starting from firmware V6, it is also possible to show special messages for a particular call as long as the Call-Id matches the current call. An example of that MESSAGE method would be:
