Summary:A method for handling user identity and privacy, wherein a first Session Initiation Protocol (SIP) proxy is about to forward a SIP request to a next SIP proxy includes the step of determining whether Transport Layer Security (TLS) is supported in a hop to a next SIP proxy. When TLS is supported, the method includes establishing a TLS connection to the hop to the next SIP proxy, requesting a certificate from the next SIP proxy, receiving the certificate, verifying the certificate and trustworthiness of a network of the next SIP proxy and retaining identity information when the certificate and the trustworthiness of the network is verified. When TLS is not supported, or when the certificate is not verified, or when the trustworthiness of the network is not verified, the identity information is removed. Thereafter, the SIP request is forwarded over the TLS connection.
