When the ’Record’ key is pressed once during a call, the phone sends a SIP INFO message with

  • Record: on

and a blinking symbol at the display indicates the running recording. Another key press stops the recording, switches the display indicator off, and makes the phone send a SIP INFO message with

  • Record: off

Please be aware that the phone is only triggering the start and end of the recording on a remote location which has to perform the recording itself. The phone does not record the voice streams at all. The recording mechanism can be configured using the setting recording_mechanism

  • Provides access to the DIALED call history list.
  • Since will auto hide when the dialed-list is empty.
  • Since and this key event is acting like OK inside a call list. So you can dial the selected number from the call history list with F_REDIAL (only when F_REDIAL is applied to an hard key).

If a key configured with Instant Redial is pressed:

  • The most recent item dialed is redialed without any additional acknowledge / confirmation - no matter handset / headset is lifted or not.
  • If the dialed list does not contain any items, it is treated as an off hook showing the dial screen.
  • F_REDIRECT can be used to create a shortcut for setting up call forwarding for the phone. If you are using a programmable function key with LED, the LED will indicate the current state of the call forwarding.

  • Example: You have set F_REDIRECT:490 to one of the programmable function keys. Pressing that key will set up call forwarding of all or specified (on busy, after timeout) incoming calls to extension 490, as indicated by the lit LED. Press the key again to end call forwarding; the LED will go out. Similar mappings to other extensions can be made in parallel on other function keys. If you are using F_REDIRECT without a number the currently set number will be used for redirection. See also Call Forwarding.
