Encapsulation allows for the original content to be transmitted without altering the original IP datagram and header contents and provides flexible allocation of additional chunks containing additional arbitrary data. The method is NOT designed\nor intended for “tunneling” of IP datagrams over network segments, and best serves as vector for passive duplication of packets intended for remote or centralized collection and long term storage and analysis.\n\n### History:\nThe protocol was originally designed by Alexandr Dubovikov and Roland Hänel for the [HOMER](http://github.com/sipcapture/homer) [SIPCAPTURE](http://github.com/sipcapture) project and is currently at its third generation _(HEPv3)_ \n\n### Integration:\nHEP is natively implemented in many leading SIP platforms:\n* [Kamailio](https://github.com/sipcapture/homer/wiki/Examples%3A-Kamailio) \n* [OpenSIPS](https://github.com/sipcapture/homer/wiki/Examples%3A-OpenSIPS)\n* [FreeSWITCH](https://github.com/sipcapture/homer/wiki/Examples%3A-FreeSwitch)\n* [Asterisk](https://reviewboard.asterisk.org/r/3207/) \n* [RTP:Engine](https://github.com/sipwise/rtpengine) \n*  ... and more!\n\nHEP is also supported by several capture tools:\n* [Captagent](http://github.com/sipcapture/captagent)\n* [Heplify](https://github.com/sipcapture/heplify)\n* [Sipgrep](http://github.com/sipcapture/sipgrep)\n* [HEPipe](http://github.com/sipcapture/hepipe)\n* [nProbe](http://www.ntop.org/products/netflow/nprobe/)\n* [sngrep](https://github.com/irontec/sngrep)\n* ... and more!\n\nHEP code examples are available for many languages:\n* [C/C++](https://github.com/sipcapture/hep-c)\n* [Javascript/Node](https://github.com/sipcapture/hep-js)\n* [Java](https://github.com/sipcapture/hep-java)\n* [Erlang](https://github.com/sipcapture/hep-erlang)\n* [Go](https://github.com/sipcapture/hep-go)\n* [Perl](https://github.com/sipcapture/hep-perl)\n* [Python](https://github.com/sipcapture/hep-python)\n\n\n\n### Support\nFor any inquiry related to HEP/EEP please contact [support@sipcapture.org](mailto:support@sipcapture.org)\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsipcapture%2FHEP","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsipcapture%2FHEP","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsipcapture%2FHEP/lists"}
