Event:
When the phone receives the SIP NOTIFY, it will trigger the action uri xml sip notify parameter,if it has been previously configured using the configuration files or the Aastra Web UI. If the action uri xml sip notify parameter is not configured, the phone does not do anything.
On the phone side, a System Administrator can enable or disable this SIP
NOTIFY feature using the configuration files or the phone Web UI.
Also to ensure that 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, the phone rejects the message.
