SRTP and Transcoding

Secure Real Time Transport Protocol (SRTP) allows secure media transmission. Transcoding is the ability to convert between media streams that are based upon different codecs. The Oracle® Enterprise Session Border Controller supports IP-to-IP transcoding for SIP sessions and can connect two voice streams that use different coding algorithms with one another. Both SRTP and transcoding are available in the same call. This feature is not available on the Acme Packet 4500.

As of this release of the software, SRTP and transcoding may be combined for the same call. This behavior is available by default and no extra configuration is required.
