Removing UserAgent and Server SIP Headers
Currently, the phone always configures the SIP UserAgent/Server headers to contain:
Aastra <PhoneModel>/<FirmwareVersion>
You can suppress the addition of these headers by using the following parameter in the configuration files:
• sip user-agent
Setting this parameter allows you to enable or disable the addition of the User-Agent and Server SIP headers from the SIP
stack.
You can configure this feature using the configuration files only.
