Dear friends,
It is true that the auto_calls_table keeps getting filled up with calls not dropped correctly. Each of these rows in MySQl blocks a channel. In effect your dialer speed will continue to slow down to
(total channels-blocked channels)
When you clear this table you will find a sudden clearance of all channels and the dialer will not maintain the dial ratio as specified and the ratio may jump dramatically.
We analysed this problem in depth and came up with a patch for all our installations 3 weeks back. Lo Behold ever since our dialer is behaving perfectly with no requirement to restart the server or clear the said table.
Since it is a major problem with almost all installations as can be seen from this forum, we have sent the patch to Matt for ratification and soon you should find it on this forum.
Over to you Matt.
