Hi Olivier, thanks for the detailed discussions, it's been very enlightening! Reading briefly, it looks like it's not too difficult to add basic IMS support in PJSUA-LIB, so hopefully this can be done soon (and thanks for the information on how this should be done in pjsua-lib!). Can't promise anything beyond basic support though, and especially it won't be anywhere near 90% compliant. Stuffs like PoC, that's just awful! -benny Roland Klabunde wrote: > Hi Olivier, > > thanks for the detailed discussion of the IMS topics.
