I am learning elastix on the fly and my client used vicidial with asterisk before. Does elastix include features similar to vicidial? I see in the Elastix Without Tears guide that x-lite can be tied in to elastix, so is a suite like vicidial even necessary to have a functioning pbx? If so, is there an alternative to vicidial because from reading posts here it looks like it doesn't play well with elastix. Thanks!
