3.6.4
Modify Phone Settings
To modify settings on the phone, that is, to write data items to the phone, the provisioning ser-
vice sends a message with Action set to WriteItems. The items in question are sent to the
phone in a similar fashion as described for reading data items (see Section 3.6.3.2, "XML Data
Exchange").
When the phone is in a call, it will not accept a WriteItems action. Instead, it will
>
reply with a message stating it is in busy status. Example:
<WorkpointMessage xsi:schemaLocation="http://www.siemens.com/
DLS" xmlns="http://www.siemens.com/DLS" xmlns:xsi="http://
www.w3.org/2001/XMLSchema-instance">
<Message nonce="957AE6C2E40C0E916B7CD5636480F171" max-
Items="-1" fragment="final">
<ReasonForContact status="busy"
action="WriteItems">reply-to</ReasonForContact>
</Message>
</WorkpointMessage>
When the provisioning service sends a CleanUp with a 'send-solicited' item, the
phones reaction will be to schedule an automatic solicited connection to the provi-
sioning service when the busy condition is cleared (>=V3R3). See also Section
3.7.3, "Contact-Me during Busy State".
When sending a CleanUp without a 'send-solicited' item, the phone will not inform
the provisioning service when it has returned to idle state, so the provisioning service
will have to resend the request periodically.
