Step Action
24 Enable the "XML SIP Notify" field by checking the check box.
(Disable this field by unchecking the check box. Default is disabled).
Enabling this parameter allows the phone to accept or reject an aastra-xml SIP NOTIFY message.
Note: To ensure the SIP NOTIFY is coming from a trusted source, it is recommended that you enable
the Whitelist feature (Whitelist Proxy parameter) on the IP phone. If enabled, and the phone
receives a SIP NOTIFY from a server that is NOT on the whitelist (i.e. untrusted server), the phone
rejects the message.
For information about setting this feature, see Chapter 5, the section,
page 5-316.
