Aastra Telecom REV 06 - Manual (Page 96)

Features in Release 2.2
92 RN-001029-00, Rev 06, Release 2.2
IP Phone Release Notes 2.2
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.
