206  # "TURN REST API" link in the project's page
207  # https://github.com/coturn/coturn/

209  # This option is used with timestamp:

212  # turn user -> usercombo
213  # turn password -> base64(hmac(secret key, usercombo))
214  #
215  # This allows TURN credentials to be accounted for a specific user id.
216  # If you don't have a suitable id, then the timestamp alone can be used.
217  # This option is enabled by turning on secret-based authentication.
218  # The actual value of the secret is defined either by the option static-auth-secret,
219  # or can be found in the turn_secret table in the database (see below).

557  # ALTERNATE-SERVER, with error 300, on ALLOCATE request, to the client.
558  # Client will receive only values with the same address family
559  # as the client network endpoint address family.
560  # See RFC 5389 and RFC 5766 for the description of ALTERNATE-SERVER functionality.
561  # The client must use the obtained value for subsequent TURN communications.
562  # If more than one --alternate-server option is provided, then the functionality
563  # can be more accurately described as "load-balancing" than a mere "redirection".
564  # If the port number is omitted, then the default port
565  # number 3478 for the UDP/TCP protocols will be used.
566  # Colon (:) characters in IPv6 addresses may conflict with the syntax of

569  # [2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478 .
570  # Multiple alternate servers can be set. They will be used in the
571  # round-robin manner. All servers in the pool are considered of equal weight and
572  # the load will be distributed equally. For example, if you have 4 alternate servers,
573  # then each server will receive 25% of ALLOCATE requests. A alternate TURN server
574  # address can be used more than one time with the alternate-server option, so this
575  # can emulate "weighting" of the servers.
576  #
577  # Examples:
578  #alternate-server=1.2.3.4:5678
579  #alternate-server=11.22.33.44:56789
580  #alternate-server=5.6.7.8
