Adds an extenstion to the list of supported extensions for Invite. If an incoming Invite message has a required header that does not exist in this list, it will be automatically rejected with 420. Once an item is added to this list, it cannot be removed. This list does not affect outgoing Invites for which the application is responsible for adding any necessary headers such as "Supported" or "Require" headers for specific SIP extensions.

Terminates the endpoint and cleans up active sessions and resources. The endpoint is no longer usable.

Starts an asynchronous process to unregister the current endpoint. This method always succeeds.

Completes the asynchronous Register operation.

Waits for the pending SendMessage operation to complete.

Completes the asynchronous Terminate operation.

Finishes the asynchronous Unregister operation.

Gets the value of the given parameter.

Gets the list of extensions supported by this endpoint. By default, this list is populated with extensions understood by the platform. The application can add other extensions it can support. Incoming Invite messages will be automatically rejected with 420 response if it contains a Requires header with option-tag that is not present in this list.

Event handler for incoming notify request.

Register for page mode messages.

Removes a feature parameter matching the name if it exists.

Terminates the endpoint and cleans up active sessions and resources. The endpoint is no longer usable.

Returns the string representation of the object.

Synchronously unregisters the endpoint. It is not recommended for a UI thread.

Unregister for pagemode messages

The default realm used when communicating with the server. This realm is used when adding a NetworkCredential to the CredentialCache.

Specifies the allowed set of authentication protocols to be used for this endpoint.

Gets the flag that indicates whether the client allows communicating with a server that does not challenge messages from this client.

Gets or sets the application context.

Gets or sets the application user agent string. This is appended to the user agent header.

The authentication protocol currently in use with the server. If there is no security context established with the server, the default value of SipAuthenticationProtocols.None is returned.

Gets or sets the connection manager.

This property returns a credentials cache that can be used by the application to supply credentials needed to authenticate the application with servers.

Gets the default domain of the endpoint URI.

Gets or sets the desired session timer interval of the application. This is used only for the initial Invite or Response.

Gets or sets the flag that indicates if the endpoint should retry requests for failed responses that contain retry-after header. By default, this is false and hence the platform will retry once more for such requests. If the applications wants to disable this automatic retry behavior, this property can be set to true. Typicaly, this might be needed for an application whose primary task is to perform back to back operation for two sessions where automatci retry might interefere with the ability to offer quick feedback via the back to back seesion so that the remote can take corrective measures.

Disables signing of Referred-By headers for endpoint if configured to use MTLS.

Gets or sets the value that controls whether automatic register refresh should be allowed due to connection drop. When the current connection is disconnected for some reason and the endpoint uses either client connection manager or a server connection manager that does not listen, a register refresh attempt is made. By default, this property is set to false (Register Refresh occurs when connection drops). If disabled, connection drop would set the registration state to Unregistered. This flag is ignored when the server connection manager is used and the manager is listening for incoming connections as there is no automatic register refresh attempted.

Gets or sets the user name preferred by the application for the local user. This name will be used as the display name of the user in outgoing messages. This property indicates the display name to use in outgoing messages.

Gets the GRUU of the endpoint, if any. Can be null.

Represents the ID for this endpoint. The same URI may be used on different endpoints. The ID is unique across all endpoints having the same URI.

Gets or sets value indicating if recovery attempt from failure in a dialog's signaling path is supported

Gets or sets the Boolean value indicating if the endpoint should be throttled or not.

Gets or sets the default policy used for the session timer. This value is inherited by incoming/outgoing sessions unless an incoming session requires it. The application can override the policy per session.

Gets or sets the value that controls the number of redirect attempts allowed for registration. The default value is 3. The allowed range is from 0 to 5. The value of 0 disables automatic redirection.

Maximum duration in minutes to wait for final response.

Gets or sets the minimum session interval. Any session-expires interval less than this value in messages will not be accepted.

Gets or sets the methods supported by this endpoint to be specified in the Register message. By default, this is set to support subscription and signaling sessions. The application should normally set this property before calling the Register method. If this is set after the Register method is completed, it will take effect when a Register refresh occurs.

Gets the Registration state of endpoint.

Gets or sets the default policy for supporting 100rel extension feature. If an application supports this then the remote can ask for this when sending provisional responses which will result in PRACK message geting sent to acknowledge the response. An application should set this to set the policy globally for all sessions created. For outgoing session, ExtensionFeatureSupport.Required is not recommended since it is not meaningful and it likely to be rejected by the remote side with 420 (BadExtension) response.

Gets the server currently used by the endpoint.

Gets the port used to connect to the server. This is the port currently used to connect to the server or the port configured by the application if there is no active connection to the server. If the server is unknown, then 0 is returned.

Gets the sipInstance parameter value used in the contact header for Register (used by the server to generate the GRUU).

Get the syncroot of this endpoint.

Gets the transport type used for connecting to the server. This is the same as what is specified by the application or the transport used for connecting to an autodiscovered server. In case of autoconfiguration, this property will change only after a successful connection to the server.

Represents the URI of the identity owning this endpoint.

Gets the user agent string used for messages. This includes the platform's header followed by the header supplied by the application, if any.

Gets the universally unique identifier.

Raised when the protocol used between the client and server changes.

Raised when a message is received.

Raised when the Registration state changes.

Raised when the server is changed, as when the server is autodiscovered or when redirection occurs.

Raises the server port is changed, as when the server is autodiscovered or when redirection occurs.

Raised when a new invitation is received.
