  7. # Kamailio (OpenSER) SIP Server v5.4 - default configuration script
  8. # - web: https://www.kamailio.org
  9. # - git: https://github.com/kamailio/kamailio
  10. #
  11. # Direct your questions about this file to: <sr-users@lists.kamailio.org>
  12. #
  13. # Refer to the Core CookBook at https://www.kamailio.org/wiki/
  14. # for an explanation of possible statements, functions and parameters.
  15. #
  16. # Note: the comments can be:
  17. # - lines starting with #, but not the pre-processor directives,
  18. # which start with #!, like #!define, #!ifdef, #!endif, #!else, #!trydef,
  19. # #!subst, #!substdef, ...
  20. # - lines starting with //
  21. # - blocks enclosed in between /* */
  22. # Note: the config performs symmetric SIP signaling
  23. # - it sends the reply to the source address of the request
  24. # - remove the use of force_rport() for asymmetric SIP signaling
  25. #
  26. # Several features can be enabled using '#!define WITH_FEATURE' directives:
  27. #
  28. # *** To run in debug mode:
  29. #!define WITH_DEBUG
  30. # - debug level increased to 3, logs still sent to syslog

  32. #
  33. # *** To enable mysql:
  34. # - define WITH_MYSQL

  61. # - start RTPProxy:
  62. # rtpproxy -l _your_public_ip_ -s udp:localhost:7722
  63. #
  64. # *** To use RTPEngine (instead of RTPProxy) for nat traversal execute:
  65. #!define WITH_RTPENGINE
  66. # - install RTPEngine: https://github.com/sipwise/rtpengine
  67. # - start RTPEngine:
  68. # rtpengine --listen-ng=127.0.0.1:2223 ...
