IPv6-IPv4 Internetworking
The Oracle® Enterprise Session Border Controller supports the following internetworking environments:
SIP-TLS IPv6 endpoints with SIP-TLS IPv4 endpoints
SIP-TLS IPv6 endpoints with SIP-TLS IPv6 endpoints
SIP-TLS IPv6 endpoints with non-SIP-TLS (unencrypted) IPv4 endpoints
SIP-TLS IPv6 endpoints with non-SIP-TLS (unencrypted) IPv6 endpoints
SIP-TLS IPv4 endpoints with non-SIP-TLS (unencrypted) IPv6 endpoints
Note:
Previously delivered TLS functionality, for example, support for certificate extensions, and support for certificate chain processing, is not affected by IPv6-IPv4 internetworking.
SRTP IPv4 IPv6 Internetworking
Internetworking IPv4 and IPv6 media while using SDES as the key exchange protocol is supported.
SRTP is defined in RFC 3711, The Secure Real-time Transport Protocol (SRTP). It provides confidentiality, message authentication, and replay protection for RTP media and control traffic. SDES is defined in RFC 4568, Session Description Protocol (SDP) Security Descriptions for Media Streams. This RFC describes a new SDP cryptographic attribute that provides a secure method to provide security for unicast media streams.
