Encrypting MRCP v2

MRCPv2 TLS

Beginning with Lumenvox version 18.0, encrypting MRCP audio and messages is supported when using MRCP v2.  This is done using the SIPS protocol to establish encryption for a new MRCP session using standard TLS methodology.  The MRCP messages are encrypted using TLS.  The audio traffic is encrypted using the SRPT protocol.

The SIPS begins on a different port than standard MRCP, the default value is 5061.  see sips_port

Public key certificates need to be specified for both SIPS and MRCPvs/TLS.  By default, self signed certificates created during installation are used, alternate certificates should be specified via configuration.   see sips_ssl_cert_file  and  mrcp_tls_cert_file

If desired, the allowed encryption ciphers can be limited via configuration   see sips_cipher_list  and  mrcp_tls_cipher_list
