Check-synch enhancement (IP Office 8.0)
The Remote Check for Update feature allows SIP servers to start a check for an update
remotely using the event called check-sync. This feature enables the IP Deskhones to be
updated with the latest firmware/configuration files present on the provisioning server. This
feature is enabled/disabled using the REMOTE_CHECK_FOR_UPDATE parameter in the
Device Configuration file.
SIP 4.3 provides the following check-sync functionality enhancements:
• allows a server to upgrade configuration files separately on request from the server
• firmware updates are performed transparently for a user (the old mechanism required
user confirmation before performing the firmware update)
• Changes to the [LANGUAGE] or [DIALING_PLAN] section of the Provisioning file trigger
a NOTIFY message to the IP Deskphone. If REMOTE_CHECK_FOR_UPDATE is
enabled, then a firmware download occurs. The user is able to use the IP Deskphone
while dialing plans and language files are updated.
Answer-after parameter (IP Office 8.0, ABG 5800 6.2)
To support Click-to-Dial and Push-to-Talk applications, an application platform such as One-X
portal must be able to originate calls that force the endpoint off-hook, without end-user
intervention
To support this functionality, SIP 4.3 introduces the answer-after parameter. When present in
the Call-Info header of an incoming INVITE request, it indicates how many alert cycles are
applied before the call is automatically answered. If the answer-after value is 0, then the call
is automatically answered without applying any alert tones.
The answer-after parameter is ignored if:
• the IP Deskphone that does not support speakerphone; it cannot automatically answer
the call, and must wait for the user to actively answer the call.
• the IP Deskphone has a speakerphone, but the user has enabled a local privacy policy
that rejects or ignores all answer-after requests
To activate the answer-after parameter, the INTERCOM_PAGING parameter must be
enabled.
The IP Deskphone should not ring when the answer-after event has an attribute configured as
0. The tone is played from the IP OOffice / ABG 5800.
