The Standard Interchange Protocol is a proprietary standard for communication between library computer systems and self-service circulation terminals. Although owned and controlled by 3Mthe protocol is published and is widely used by other vendors.
SIP version 1. Version 2.
What is SIP?
SIP is a simple protocol in which requests to perform operations are sent over a connection, and responses are sent in return. The protocol explicitly does not define how a connection between the two devices is established; it is limited to specifying the format of the messages sent over the connection.
The protocol specifies messages to check books in and out, to manage fee payments, to request holds and renewals, and to carry out the other basic circulation operations of a library. SIP has no built in encryptionso steps need to be taken to send the connection through some sort of encrypted tunnel. From Wikipedia, the free encyclopedia.

Such extension modules are often called bindings for the library. For example it is also used to generate wxPython, the Python bindings for wxWidgets.
SIP comprises a set of build tools and a sip module. Several extension modules may be installed in the same Python package. Extension modules can be built so that they are are independent of the version of Python being used. In other words a wheel created from them can be installed with any version of Python starting with v3. The sip module provides support functions to the automatically generated code. The sip module is installed as part of the same Python package as the generated extension modules.
Unlike the extension modules the sip module is specific to a particular version of Python e. The documentation for the latest release can be found here.

Related software eXosipGPL. This is a library based on oSIP. It contains a high layer easier to use for implementing SIP End point. Nevertheless, this is optional. It contains various "How-to" in the module page which you will find usefull if you are using osip for the first time.
There is also some general notes on the main page that describes history and available features of the GNU oSIP stack. Old documentation is still available in ps and pdf format: in pdf format. The new one can be rebuilt with the DoxyGen tools. The old osip atosc.It combines signaling protocol SIP with rich multimedia framework and NAT traversal functionality into high level API that is portable and suitable for almost any type of systems ranging from desktops, embedded systems, to mobile handsets.
PJSIP is both compact and feature rich.
Top five Open Source Sip Libraries
It supports audio, video, presence, and instant messaging, and has extensive documentation. PJSIP is very portable. On mobile devices, it abstracts system dependent features and in many cases is able to utilize the native multimedia capabilities of the device. PJSIP has been developed by a small team working exclusively for the project sincewith participation of hundreds of developers from around the world, and is routinely tested at SIP Interoperability Event SIPit since SIP over WebSocket transport.
Easy to use and powerful user API. JS Version 0. With SIP. It is also called sip user-agent library. It is used for communication like person to person,instant messaging IM ,Voice over interenet protocol VoIP and real time communication.
It is also used for making SIP client software. Sofia-Sip is based on Sip Stack. Sofia-SIP included the features of early media,sessions,session timers,provisional response,caller preferences etc.The New SIP Stack in Asterisk

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Does not necessarily need to be free. Has anyone used anything good? I am really looking for more than a google search on this one. To clarify further, I am looking for a library that would help me to implement a SIP proxy server without having to manually construct the SIP packets. I'm not looking for asterisk, freeswitch or any other pbx software.
I am looking to create a service in Cthat will wait for SIP packets and respond to them and I would like a library that would handle most of the details.
I went through a similar quest 7 years ago, but looking for an embedded C version. I looked at the oSIP library. It did all the work of converting SIP packets to structures and back. However, one point in the documentation stuck with me. The author recommended that you become very familiar with the SIP specification RFC to use the library effectively.
After reading the specs several times, I ended up writing my own parser and call control application. Keep in mind that SIP is still an evolving standard. Interoperability is tough. Different end-points use different ones, and interpretations of the specs are not always compatible. There are several different interoperability "test events like SIPit to make sure your implementation works with others. Whatever you select, make sure you have a good understanding of the specs for the features you are implementing.
You also need a media layer to handle audio unless your application is purely a SIP proxy. It is very configurable and has a high success rate for compatibility. It is written in very portable C and has a number of wrappers. Here is a. NET wrapper that works really well.
