DefaultRTCClassAttribute

The DefaultRTCClassAttribute class indicates which derived class to use in place of a standard SIP class. For example, a custom class to handle SIP responses can be designated with this attribute, as long as the new response class inherits from the Response class. To use DefaultRTCClassAttribute, the custom class must inherit from one of the following classes:

• Request
• Response
• ClientTransaction
• ServerTransaction

The DefaultRTCClassAttribute class is derived from the System.Attribute class.
