SAP-3756: In a certain multicast scenario when a caller (B) is accepted by a phone (A) that receives already a multicast page, the caller cannot hear the audio from callee (A). This issue is isolated to D717, D735 & D335.

→ No workaround

SAP-4680: For refactoring purposes the maximum amount of entries in the local phone book is temporarily reduced from 2000 to 1000 @D715 @D717 D725 @D735

→ No workaround. Please make sure that you do not use this version of you need > 1000 local phone book entries with the affected models.

SAP-4459: If an Action URL is configured for an phone-book contact that contains e.g.: /nphMotionJpeg?Resolution=640x480#mjpg the action is triggered, but the phone sends a malformed request, - which partially defects e.g. MJPEG door-phone integration

→ No workaround, except configuring the URL on an fkey and manually request the MJPEG from the door-phone with key press

Note: Integrations where the Action URL does end with a plain text e.g. /snoma.cgi as described in Automatic view Door Camera on Doorbell ringing are not affected

SAP-4239: The setting transfer_dialing_on_transfer is not effective anymore. Even if set to attended the transfer performed will be a blind transfer

→ Workaround: we recommend using the new context-sensitive key "Attended" to perform an attended transfer, please see SAP-3692 listed in New features below.
