Hello,
It works also for me with UDP contacts, thank you. One more thing I noticed
- by using *db_mode=1* and *db_load=1* after restarting Kamailio it's not
loading anymore all contacts from the DB or it's loading but then keepalive
module it's removing them from the local memory, I believe this is because
keepalive doesn't know the status of the extension, will be nice to have
that fixed as well.
Regards,
Ilie.
