This provides binding to the GNU osip2 library and the eXosip2 stack. This will allow writing of event driven SIP applications in the Go language. The eXosip2 stack has a high level of interop conformance and has been extensively used for over two decades in both open source projects and commercial products.
This implimentation offers a very small subset of eXosip2 functionality both as proof of concept for integrating eXosip2 with Go, and to jump-start further development. There is a lot of cgo bridging code, especially for event structures. However, given that other open source SIP conformat stacks in pure Go seem either to still be very incomplete or have been entirely abandoned many years go, this may actually prove more viable for Go SIP development.
