Aastra Web UI
Enabling/Disabling the XML SIP NOTIFY Feature
1
Click on Advanced Settings->Global SIP->Advanced SIP Settings.
2 The “XML SIP Notify" field is disabled by default. To enable this field, check the box.
This field enables or disables 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.
