Move the GCM srtp cipher suites below the default SRTP_AES128_CM_SHA1_80 one. This will not negotiate them by default since they have an impact on packet overhead for audio-only calls. GCM can still be negotiated if the peer offers it as preferred cipher suite or answers with just that cipher suite.
