GoAutodial Minor issue Trouble Shooting

I am running GoAutodialer, Everything was working fine. This morning I saw the disk was full. I have deleted all the logs in /var/log folder and I have also deleted all the recordings. Restarted the server and when agen logs in the softphone is not ringing. I see the calls are coming in but not coming to the agents since the softphone is not ringing when the login. I saw your posts and checked the ingroup, all the agents were selected in it. From your another post I tried repairing the db. IT says all tables are ok and optimized. But still the softphone is not ringing when the agent logs in.
