// ============================================================================ // Description: // This program provides a minimal example of how to use the SIP Sorcery SIP stack // to initiate a call to an external user agent. The example sets up the SIP transport // and then fires off an empty INVITE request to the destination SIP user agent.  // No media is negotiated and no incoming SIP requests are handled. // // Author(s): // Aaron Clauson // // License:  // This software is licensed under the BSD License http://www.opensource.org/licenses/bsd-license.php // ============================================================================ using System; using System.Net; using SIPSorcery.SIP; using SIPSorcery.SIP.App; using SIPSorcery.Sys; namespace SIPSorcery.Test { class Program { // The SIP stack internals will bubble log messages up. use this delegate to spit them out to the console. private static SIPMonitorLogDelegate _logDelegate = (evt) => { if (evt is SIPMonitorConsoleEvent) { Console.WriteLine(((SIPMonitorConsoleEvent)evt).ToConsoleString("*")); } }; static void Main(string[] args) { try { Console.WriteLine("SIPSorcery Example:"); // Set up the SIP transport infrastructure.
