The User-Agent header can contain the product name and product version
number of the UAC in a SIP request message, while the Server header can contain
the product name and product version number of the UAS in a SIP response
message. Revealing the specific software version of the user agent and server
might allow the user agent and server to become more vulnerable to attacks
against software that is known to contain security holes. Therefore, it is stipulated
in RFC 3261 that the User-Agent header field and the Server header field should
both be a configurable option.
