I’ve noticed something with Asterisk 1.4.2 concerning presence and setting qualify=yes. When qualify=yes is enabled for a friend in sip.conf presence does not seem to work properly. I am able to confirm this by verifying that the contents of the subscription table is empty in asterisk (show subscriptions). If I comment out qualify=yes for the friend presence works properly and the subscription table is not empty.
Has anyone else noticed this? I want to use qualify=yes to handle NAT issues but also want the presence stuff to work as well.
