Same as the current implementation. This feature does not need specific
activation to be supported. With using the current parameter, it is to avoid
messages attacks from non desired sources.
The 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.
