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.
Configuring UserAgent/Server SIP Headers

header is added to the SIP stack.
• sip user-agent
Configuration Files

Setting” on page A-176.
