Kevin Harwell commented on ASTERISK-27481:
------------------------------------------

I believe I've duplicated your issue. It appears that you do not have res_pjsip_pubsub.so loaded.  Try loading that module and see if that fixes the problem. If you have disabled it via menuselect then enable it. If you have disabled (noload) it via modules.conf then allow it to load.
