Ability to Remove UserAgent and Server SIP Headers
Currently, the phone always configures the SIP UserAgent/Server headers to
contain:
Aastra <PhoneModel>/<FirmwareVersion>
A new feature has been added to Release 2.1 that allows an Administrator to
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.
An Administrator can configure this feature using the configuration files only.

You use the following parameter to specify whether the UserAgent and Server SIP
header is added to the SIP stack.
