The Single Line Dialer is an upgraded and more robust feature product than the preview dialer. Here are a list of the features:

Preview Line Dialer:

• Fewer Minutes

• Call lines: 1

• Timezone Protection

• Click to Call

• Choice ID

• Calls via Computer or Phone

• Call Recording

• Call Campaigns

Single Line Dialer:

• More Minutes

• Call lines: 1

• Timezone Protection

• Smart Voicemail Drop

• Click to Call

• Choice ID

• Calls via Computer or Phone

• Call Recording

• Call Campaigns

Preview Line Dialer is great for someone looking to have a click to call and dial function right within their contacts. The Preview Line Dialer however does miss some more enterprise features like Smart Voicemail Drop or the advanced dialing mode. Without advanced dialing, the Preview Line Dialer is more interactive, and requires you to click to navigate between leads and click to dial each number.

Single Line Dialer is great for someone looking to really take advantage of the features of a more advanced calling product and call even more numbers in less time.
