[SFLphone] TLS and SRTP support

[Wang, Waylon]

Does SFLPhone support TLS and SRTP? If not, how do I accomplish the following from the SFLPjone (maybe some coding required)?

$ ./pjsua --use-tls --tls-ca-file root.pem --tls-cert-file server-cert.pem --tls-privkey-file privkey.pem               //as a TLS server or
$ ./pjsua --use-tls sip:SERVER;transport=tls                                                                            //as a TLS client
$ ./pjsua --use-tls --use-srtp=1 sip:alice at example.com;transport=tls                                                    //using srtp

Thanks!
