The DNC Phone Quality Scores (also referred to as Sonar Scores) predict the likelihood that a phone number connects to the voter you wish to contact AND that you can have a conversation (collect info) from that voter.


Scores are broken into five (5) buckets:

- Very Low (Bottom 10%)    - Low (10 to 25%)    - Medium (25 to 50%)    - High (50 to 75%)        - Very High (Top 25%)


When using these score buckets, campaigns can expect to find that excluding lower scored phones will still result in users having high success rates. 


For instance, if a campaign calls all 10,000 numbers in their universe without narrowing to phone scores, we'd expect them to have 240 conversations. 

However, if they narrow to the top 4 buckets (excluding 'Very Low'), they'd call 9000 numbers and we'd still expect 240 conversations. 

If a campaign called the top 3 buckets (excluding 'Very Low' and 'Low') with 7600 numbers, we'd still expect them to have 235 conversations despite excluding 24% of contacts.
