Encryption- SIP can encrypt headers and message bodies to prevent a third party from getting information from them. TLS uses hop-by-hop encoding. That is, each hop (UAC to Proxy, Proxy to Location Server, Proxy to UAS, etc.) establishes its own keys with the next hop.

Encryption would ensure that only carriers
possessing a particular decryption key are capable of inspecting encapsulated ISUP MIME bodies in a SIP request.
SIP-T endpoints MUST support S/MIME signatures (CMS SignedData), and SHOULD support encryption (CMS EnvelopedData).
And end-to-end encryption achieved in SIP is by SMIME.
