With an inbound call tracking software it is possible to track both inbound and outbound calls. Inbound calls are calls received from leads and call history tracking software tracks, records and logs calls for marketing purposes. Outbound calls include calls that have been made from a business's VOIP soft console or business's phone to a prospect for lead qualification and nurturing. You can have specific inbound call tracking software or an outbound call tracking system depending upon the nature of the majority of your business calls.
