2）设置通讯时编码，必须先编译并加载：  codecname[@8000h|16000h|32000h[@XXi]]
       XX is the frame size must be multples allowed for the codec FreeSWITCH can support 10-120ms on some codecs.
       We do not support exceeding the MTU of the RTP packet.

       iLBC@30i         - iLBC using mode=30 which will win in all cases.
       DVI4@8000h@20i   - IMA ADPCM 8kHz using 20ms ptime. (multiples of 10)
       DVI4@16000h@40i  - IMA ADPCM 16kHz using 40ms ptime. (multiples of 10)
       speex@8000h@20i  - Speex 8kHz using 20ms ptime.
       speex@16000h@20i - Speex 16kHz using 20ms ptime.
       speex@32000h@20i - Speex 32kHz using 20ms ptime.
       BV16             - BroadVoice 16kb/s narrowband, 8kHz
       BV32             - BroadVoice 32kb/s wideband, 16kHz

3） 当使用SRTP时，关键是您不提供或接受可变比特率编解码，这样做将泄露信息并可能损害您的SRTP流
 Supported SRTP Crypto Suites:
      AEAD_AES_256_GCM_8
      :::This algorithm is identical to AEAD_AES_256_GCM, except that the tag length, t, is 8, and an authentication tag with a length of 8 octets (64 bits) is used. An AEAD_AES_256_GCM_8 ciphertext is exactly 8 octets longer than its corresponding plaintext.
      AEAD_AES_128_GCM_8
      :::This algorithm is identical to AEAD_AES_128_GCM, except that the tag length, t, is 8, and an authentication tag with a length of 8 octets (64 bits) is used. An AEAD_AES_128_GCM_8 ciphertext is exactly 8 octets longer than its corresponding plaintext.
      AES_CM_256_HMAC_SHA1_80 | AES_CM_192_HMAC_SHA1_80 | AES_CM_128_HMAC_SHA1_80
      :::AES_CM_128_HMAC_SHA1_80 is the SRTP default AES Counter Mode cipher and HMAC-SHA1 message authentication with an 80-bit authentication tag. The master-key length is 128 bits and has a default lifetime of a maximum of 2^48 SRTP packets or 2^31 SRTCP packets, whichever comes first.
      AES_CM_256_HMAC_SHA1_32 | AES_CM_192_HMAC_SHA1_32 | AES_CM_128_HMAC_SHA1_32 
      :::This crypto-suite is identical to AES_CM_128_HMAC_SHA1_80 except that the authentication tag is 32 bits. The length of the base64-decoded key and salt value for this crypto-suite MUST be 30 octets i.e., 240 bits; otherwise, the crypto attribute is considered invalid.
      AES_CM_128_NULL_AUTH
      :::The SRTP default cipher (AES-128 Counter Mode), but to use no authentication method.  This policy is NOT RECOMMENDED unless it is unavoidable.

SRTP variables that modify behaviors based on direction/leg:
      rtp_secure_media
      :::possible values:
          mandatory - Accept/Offer SAVP negotiation ONLY
          optional  - Accept/Offer SAVP/AVP with SAVP preferred
          forbidden - More useful for inbound to deny SAVP negotiation
          false     - implies forbidden
          true      - implies mandatory
          default if not set is accept SAVP inbound if offered.
      rtp_secure_media_inbound | rtp_secure_media_outbound
      :::This is the same as rtp_secure_media, but would apply to either inbound or outbound offers specifically.

How to specify crypto suites:
      By default without specifying any crypto suites FreeSWITCH will offer crypto suites from strongest to weakest accepting the strongest each endpoint has in common.  If you wish to force specific crypto suites you can do so by appending the suites in a comma separated list in the order that you wish to offer them in.
      Examples:
          rtp_secure_media=mandatory:AES_CM_256_HMAC_SHA1_80,AES_CM_256_HMAC_SHA1_32
          rtp_secure_media=true:AES_CM_256_HMAC_SHA1_80,AES_CM_256_HMAC_SHA1_32
          rtp_secure_media=optional:AES_CM_256_HMAC_SHA1_80
          rtp_secure_media=true:AES_CM_256_HMAC_SHA1_80
     Additionally you can narrow this down on either inbound or outbound by specifying as so:
          rtp_secure_media_inbound=true:AEAD_AES_256_GCM_8
          rtp_secure_media_inbound=mandatory:AEAD_AES_256_GCM_8
          rtp_secure_media_outbound=true:AEAD_AES_128_GCM_8
          rtp_secure_media_outbound=optional:AEAD_AES_128_GCM_8

      rtp_secure_media_suites
      Optionaly you can use rtp_secure_media_suites to dictate the suite list and only use rtp_secure_media=[optional|mandatory|false|true] without having to dictate the suite list with the rtp_secure_media* variables.

4）xmpp_client_profile can be any string.
    xmpp_server_profile is appended to "dingaling_" to form the database name containing the "subscriptions" table.
    used by: dingaling.conf.xml enum.conf.xml

5） Digits Dialed filter: 
       The digits stream may contain valid credit card numbers or social security numbers, These digit
       filters will allow you to make a valant effort to stamp out sensitive information for
       PCI/HIPPA compliance. (see xml_cdr dialed_digits)
       df_us_ssn   = US Social Security Number pattern
       df_us_luhn  = Visa, MasterCard, American Express, Diners Club, Discover and JCB

6）SIP 和 TLS 的设置参考 http://wiki.freeswitch.org/wiki/Tls
     可用： sslv2,sslv3,sslv23,tlsv1,tlsv1.1,tlsv1.2
     默认： tlsv1,tlsv1.1,tlsv1.2

7）TLS cipher suite 默认： ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH
   实际值是每个平台不同的，要查看哪些可用：openssl ciphers -v 'ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH'
