There has been some work on cleaning up the eXosip2 api bindings in sipwitch and antisipate. This lead to releasing sipwitch 1.7.0.
I am also adopting libruli to do srv lookups of sip services. Interestingly, while libruli is in Debian (stable), it is not presently packaged in fedora.
Antisipate now has some cli utilities starting with sip-ping. Some of the rest will be introduced to test and debug specific facilities of sipwitch. In particular I plan to make and use sip-selfinvite to validate registration and sdp rewrites as we work on sipwitch media packet reflection for nat support and auto-network detection.
