Teleblend Service includes access to Directory Assistance.

Just dial 411 or (area code) 555-1212 to research nationwide phone numbers, addresses, and more. The cost to dial is just $.79 per use and you can get up to two listings each time you call. That's much less than you'll pay with traditional phone service or even with other VoIP services. 

PLUS, with any unlimited calling plan you get two FREE Directory Assistance calls included every month. That's a savings of $1.58!
