Detailed Description

This class is used to create a thread to run the SipStack in.

The thread provides cycles to the SipStack by calling process. Process is called at least every 25ms, or sooner if select returns a signaled file descriptor.

Deprecated:

This is a deprecated method of giving the SipStack cycles. The current canonical example is EventStackThread.
