            Description

            When libsrtp can be updated to use openssl and a version of libsrtp that supports AES-GCM:

            http://jira.freeswitch.org/browse/FS-5422

            FreeSWITCH will already be able to realize some performance improvements with CPUs that support AES-NI. However, the real win is using AES-GCM mode:

            I'm told there is already a patch to implement this for pjsip. It would be nice to get this implemented in FreeSWITCH as well.
