Kamailio and SIP Router Integration

This page keeps track of where parts and functionalities from Kamailio are moved to work with SIP Router.

Database API

The database API existing in Kamailio was moved as library in:


MI (Management Interface)

The MI API was moved as library in:


The MI commands exported by core were not ported yet. They will be moved in a module.


Statistics API was moved as library in:


Statistics variables exported by core were not ported yet.

During discussions on devel lists, the statistics API is planned for a redesign to avoid performance penalties.

Test suite

Included in the test/unit directory, porting is under way at the moment.

Setup scripts

Not yet included in the sip router repository.

TM and Core Extensions

All modules apart of TM have been completely included in SIP Router, therefore no feature has been lost.

For TM and core, the versions of SIP Router have features that are not present in Kamailio (OpenSER), but they miss some available there. This section tries to collect them and assign priority by usage, to guide developers integrate first the most used features.

The Kamailio (OpenSER) extensions will be integrated in:

  • TM module (modules/tm)
  • TMX module (module_k/tmx)
  • KEX module (modules_k/kex)
  • PV module (modules_k/pv)
  • core
