Unable to find key '3001' in family 'SIP/Registry'

I have recently started to dabble in Realtime again with v1.4.0, but seem to have some issues with getting it working. Per the subject I am getting the following, without the ability to register from my SIP endpoints:

[code]*CLI> [Feb 2 14:05:08] DEBUG[3139]: res_config_mysql.c:651 mysql_reconnect: MySQL RealTime: Everything is fine.

After some Googling, I did throw these in my sip.conf for good measure, but without an apparent impact:

rtcachefriends=yes rtnoupdate=yes rtautoclear=yes

Any ideas?
