The minimum requirement is that lead generators set-up one campaign for web forms, and a separate campaign for call centers.
The decision to use more than the minimum based on campaign type will depend on how you want to utilize Jornaya information. There are potential advantages that come with utilizing multiple campaigns, though. Each campaign has its own unique settings that could be applied across several web sites. Additionally, campaigns provide a valuable data point on which analysis can be provided.
However, the more campaigns you create, the more maintenance there can be.
