• Easily schedule a call-back from the advertiser when the line is busy.
• Easily save the number to their phone’s contact list.
• Choose from two different numbers to call.
• Click through to your mobile site instead of calling.

Correct answer is:

• Click through to your mobile site instead of calling.
