Call Rate is one of the measurements that we use to assess agent performance.
It takes into account the total number of leads you have received over the past 42 days, compared with how many of them have turned into a connected phone call with the lead. The resulting percentage is your Call Rate.
Note that connected phone call is defined as a conversation where you speak to a person. Leaving a voicemail does not qualify as having connected with a lead.
The accuracy of your call rate is dependent upon your updating the CRM with your calling activity.
