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

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

sip user-agent

Configuration Files

For the specific parameter you can set in the configuration files, see Appendix A, the section, “User-Agent Setting” on page A-176.
