Gets or sets relative time after which the message (or content) expires. Value -1 means that value not specified.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Gets or sets initiator of the request. Value null means not specified.

Serves as a hash function for a particular type. GetHashCode() is suitable for use in hashing algorithms and data structures like a hash table.

Gets the Type of the current instance.

Gets direct access to header.

Gets the In-Reply-To header fields which enumerates the Call-IDs that this call references or returns.

Parses SIP message from specified byte array.

Gets or sets limit the number of proxies or gateways that can forward the request to the next downstream server. Value -1 means that value not specified.

Creates a shallow copy of the current Object.

Gets or sets mime version. Currently 1.0 is only defined value. Value null means not specified.

Gets or sets minimum refresh interval supported for soft-state elements managed by that server. Value -1 means that value not specified.

Gets or sets organization name which the SIP element issuing the request or response belongs. Value null means not specified.

Gest or sets priority that the SIP request should have to the receiving human or its agent. Value null means not specified.

Gets an proxy authentication challenge.

Gest credentials containing the authentication information of the user agent for the proxy and/or realm of the resource being requested.

Gets proxy-sensitive features that must be supported by the proxy.

Gets the Record-Route header fields what is inserted by proxies in a request to force future requests in the dialog to be routed through the proxy.

Gets logical return URI that may be different from the From header field.

Gets options that the UAC expects the UAS to support in order to process the request.

Gets or sets SIP response code.

Gets or sets how many seconds the service is expected to be unavailable to the requesting client. Value -1 means that value not specified.

Gets force routing for a request through the listed set of proxies.

Gets or sets the software used by the UAS to handle the request. Value null means not specified.

Gets or sets call subject text. Value null means not specified.

Gets extensions supported by the UAC or UAS.

Gets or sets when the UAC sent the request to the UAS. Value null means that value not specified.

Gets or sets logical recipient of the request. Value null means not specified.

Converts this response to raw srver response data.

Stores SIP_Response to specified stream.

Returns a String that represents the current Object.

Gets features not supported by the UAS.

Gets or sets information about the UAC originating the request. Value null means not specified.

Checks if SIP response has all required values as response line,header fields and their values. Throws Exception if not valid SIP response.

Gets additional information about the status of a response.

Gets Via header fields.The Via header field indicates the transport used for the transaction and identifies the location where the response is to be sent.

Gets or authentication challenge.
