Developers

Quick Start

1. Create a new C# Console application in Visual Studio,
2. Use the Nuget Package Manager and install the SIPSorcery package,
3. Cut and paste in the code below to send a test INVITE request to your SIP phone or softphone.

// ============================================================================
// 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.
