Description
When subscription fails this settings describes the value in
seconds after which the phone will try again. Be aware: don't
confuse this setting with the SUBSCRIBE expiration, which
is defined by user_subscription_expiry
This setting enables support for the hookflash feature on
Broadsoft's Broadworks servers. When enabled the phone
will process incoming INFO messages with a content type of
'application/broadsoft' for call waiting indication.
Additionally, when the line key is pressed in the connected
state, a hookflash event is sent to the server inside an INFO
message. This occurs in lieu of the hold action which is
usually invoked when this feature is disabled.
When this is disabled, invites for audio-calls will not be
accepted by this identity. A non-voice-identity will
automatically force setting hide_identity to be enabled.
When this setting is 'off', all incoming dialog subscriptions
for this identity are rejected with a '403 Forbidden' response.
In other words, other users are blocked from monitoring
your extension.
For this setting to have any effect,
user_allow_inc_dialog_subscribe must be on. It allows the
user to restrict extension monitoring to a group of users
using one of two possible mechansism: shared secret or
contact group. To use the shared secret mechanism simply
enter a pass phrase into this field. All users using the same
pass phrase can monitor each other's extension. Note that
this mechanism does not work with OCS/Lync. Note also
that the pass phrase must not start with '{'. The contact
group mechanism is currently available only with OCS/Lync.
Enter the name of a group on your contact list to allow all
members of that group to monitor your extension. To
distinguish a contact group from a pass phrase surround the
group name with curly braces. For example: {My Pickup
Group}. Entering empty braces {} allows everyone on your
contact list to monitor your extension (this also works with
non-OCS buddy lists).
RFC4235 the direction attribute of the XML dialog info is
optional. With this setting you can define the default value.
