I am investigating Kamailio's suitability as a SIP proxy that supports UA configuration per RFC 6080. In the lateset release (3.3), a stub implementation exists (presence_profile module) but it depends on the presence module. The presence module implements the generic SIP eventing mechanism as well as presence-specific event handling. It allows for other events to be handled via extension modules but there remains significant handling that presumes 'presence'.
I would like to support configuration of a device independent of any presence support, but this would appear to require significant refactoring of the presence module. Have I got this right?
If so, any suggestions on the best way forward?
