## Project history and usage

libeXosip2 is a C SIP endpoint library layered above oSIP. It packages higher-level call-control, registration, messaging, and presence APIs for applications that do not want to drive SIP transactions directly.

### Project history

Antisip describes oSIP and eXosip2 as open-source SIP projects started in 2001. The eXosip documentation presents libeXosip2 as the extended stack built on oSIP for quickly building compliant SIP endpoint applications.

### Adoption history

Savannah's release archive shows libeXosip tarballs in March 2005 and libeXosip2 tarballs in November 2005, followed by 3.x, 4.x, and 5.x series releases. Package managers keep it around for older and embedded VoIP software that still wants a compact GPL SIP user-agent stack.

### How it is used

The library is used to initialize an eXosip context, select UDP, TCP, TLS, or DTLS transport, and build SIP endpoint behavior such as registration, calls, transfer, messaging, and presence.

### Why package nerds care

libeXosip2 is a small but durable example of the early-2000s open SIP stack era: oSIP handles lower SIP machinery, while eXosip2 gives packagers a higher-level endpoint library and test tools.

### Timeline

- 2001: Antisip says oSIP and eXosip2 open-source projects were started.
- 2005-03-29: Savannah archive lists libeXosip 0.9.0.
- 2005-11-24: Savannah archive lists libeXosip2 2.2.2.
- 2016-09-13: Savannah archive lists libexosip2 5.0.0.
- 2021-11-22: Antisip ChangeLog and Savannah archive list eXosip2 5.3.0.
