Asterisk Auto dialer (897546)

Asterisk Auto Dialer I am currently using trixbox and sip trunks for all calls I need a dialer that can make up to 50 calls at once It needs to have an interface that allows for easy uploading of target numbers, messages and allows the number of channels to be altered mid campaign. It also needs to record the called number and any DTMF the client may make. It also needs to be able to run mutliple campaigns and be able to assign priorities to one campaign over another.
