I'm translating a form in which people can select items they'd like to volunteer for. For example: "Organize and Event."
One of the items is "Phone Banking" which refers to making phone calls, potentially in a call center. According to Wikipedia: "A political campaign strategy to collect voter data and get out the vote."
Without your input I might just use "Call Center":
Centro de Atención
But I'm not actually sure if "Phone Banking" occurs in a call center.
I bet there are other options, and look forward to your input.
