Hi Bonnie,
This is certainly possible! The best way to accomplish this in Method:Classic would be to take advantage of the List Builder (Found under the CRM Tab Group > Campaigns > List Builder)
The List builder will enable you to fill a list with your Customer leads, Create activites for these contacts, and assign them to the Method user you set up for your Call Centre. When your Call centre logs into their account, they will then see a list of every lead they need to call! Once the call has been made, they can complete the activity, assign follow ups etc...
Hopefully this helps. Let me know if you have any further questions.
Thanks Bonnie.
