So far ive experienced two problems :
1) Blank Screen on "Phone Mappings" on Wildifre 3.0.1. Downgraded to 3.0.0 and everything worked fine.
*2) User presence stays " On the Phone " even though the conversation has ended. *
Running Wildfire 3.0.0 .. Asterisk-IM-1.1.1 Asterisk Version from Ubuntu apt-get and Ubuntu Dapper Drake
