ET685 Administrator and Provisioning Manual
Description
RFC 3261 states that the number sign (#) must be encoded
inside a telephone subscriber. Therefore the default value of
the setting is 'on'. Change it to 'off' if you need special cases
for direct dialing and therefore not encoding the #.
If we subscribe, we must get a NOTIFY indicating the
current state of the dialog. But sometimes it might happen
that the NOTIFY gets lost. For handling this error state, we
introduced a new timer which monitors the receiving of the
NOTIFY. If we don't get the NOTIFY, we un-subscribe the
current subscription and set up a new fresh subscription to
get the current state and resolve the error condition.
Normally this setting should remain off. If you experience
that the BLF gets frequently out of sync (staying on to long),
or otherwise have the condition described above, you could
give this setting a try.
Accepts and processes the talk-NOTIFY also when the sdp
isn't in the received INVITE, regardless of other settings.
Call Waiting Indication combines two functions:
'Call Waiting (CW)' can be enabled ('on', 'visual

only', 'ringer') or disabled ('off'). This function allows
the phone to receive more than one call at one time.
'Call Waiting Indication (CWI)' If Call Waiting is

enabled ('on', 'visual only', 'ringer') the incoming
caller extension is displayed in the lower left corner
of the display. A short knocking signal can be heard
simultaneously in the background of your current
active call indicating another incoming call.
Starting with 8.7.5.9 Call Waiting setting is per identity.
To enable PBX specific interoperability features you may
specify the proper server type matching your PBX
environment.
