My CLI says:
-- Added contact 'sip:email@example.com:36792;transport=ws' to AOR '100' with expiration of 600 seconds -- Removed contact 'sip:firstname.lastname@example.org:36622;transport=ws' from AOR '100' due to remove_existing == Contact 100/sip:email@example.com:36622;transport=ws has been deleted -- Contact 100/sip:firstname.lastname@example.org:36710;transport=ws is now Reachable. RTT: 18.413 msec
But all the certificates are installed and placed on right places (and the transport has set to use wss). Any tips on that?
