SIP MESSAGE support (rfc 3428) for Status display
applications
More and more, services supported locally by the phone are also supported
centrally by the IP PBX or softswitch (call forwarding, call rejection, call
block …).
Unlike the local services, there is no indication on the screen when the user
activates these services on the server.
With the SIP MESSAGE method, the server could push short messages to the
phone indicating its current status. These messages will be displayed on the
phone‟s screen.
A parameter has been created with purpose to avoid attacks. Messages
coming from other servers which were not the configured one on parameter
will be rejected.
The text contained in the SIP MESSAGE body is displayed on the 4th line of
the LCD for TB30.

Feature Activation
This feature does not need specific activation to be supported. But a
parameter has been created to avoid messages attacks from non desired
sources. Parameter is AuthMessageServer. Default value is 0.0.0.0, which
means phone accepts all messages received from everywhere. Otherwise, to
limit from which server messages can be accepted, this parameter should
contain either SIP messages server IP address or domain name.
This parameter only can be configured in section [sip] of common or MAC
config files.
For example:
[sip]
...
AuthMessageServer=192.168.1.1 (or AuthMessageServer=domain.com)
