STUNOptions Property

Inherited STUN options: FINGERPRINT, SOFTWARE attribute and Authentication credentials.

Syntax

property STUNOptions: TsgcSTUNClient_Options read FSTUNOptions write SetSTUNOptions;

Default Value

—

Remarks

Inherited from TsgcSTUNClient. Controls STUN-level behaviour common to every TURN request (Allocate, Refresh, CreatePermission, ChannelBind):

• Fingerprint: when enabled, adds a FINGERPRINT attribute that lets the server distinguish STUN/TURN messages from other protocols sharing the same transport address.
• Software: when enabled, adds a SOFTWARE attribute identifying the client.
• Authentication: selects the credential mechanism (stcNone, stcShortTermCredentials or stcLongTermCredentials) and the Username/Password used when the TURN server challenges a request with a 401 Unauthorized response. TURN normally mandates long-term credentials and will reject the ALLOCATE until authentication is configured here or on TURNOptions.

Example

oTURN.STUNOptions.Fingerprint := True;
oTURN.STUNOptions.Software := True;
oTURN.STUNOptions.Authentication.Credentials := stcLongTermCredentials;
oTURN.STUNOptions.Authentication.Username := 'user';
oTURN.STUNOptions.Authentication.Password := 'secret';
oTURN.Allocate;
