Extended Key Usage (EKU) for Session Initiation Protocol (SIP)
X.509 Certificates
Abstract
This memo documents an extended key usage (EKU) X.509 certificate
extension for restricting the applicability of a certificate to use
with a Session Initiation Protocol (SIP) service. As such, in
addition to providing rules for SIP implementations, this memo also
provides guidance to issuers of certificates for use with SIP.
