Operational Features

Also to ensure that the SIP NOTIFY is coming from a trusted source, it is recommended that you enable the Whitelist fea- ture (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.

Enabling/Disabling XML SIP NOTIFY using the Configuration Files

To enable/disable the SIP NOTIFY event, you can set the following parameter in the configuration files:

sip xml notify event

If the content is missing in the SIP NOTIFY message received by the phone, the phone automatically uses the value you specify for the following parameter:

action uri xml sip notify

Configuration Files

For the specific parameter you can set in the configuration files, see Appendix A, the section, “Polling Action URI Settings” on page A-119.
