Customer service doesn’t always mean getting billing information or other enquiry details. Sometimes people call the answering service department to resolve serious issues that need a thorough knowledge on the part of the call center agent. For example, if the BPO is handling a tech support project, the agents have to be aware of the domain. They have to know the innards of a CPU well. Since general telemarketing agents will not know such technical matters, call centers hire technicians that double up as agents. They receive calls and resolve the issues of the callers on the first call itself.
There is a simple business sense in recruiting technical professionals for these projects. When the calls made at the answering desk are passed around to get someone capable to answer the call, the callers get frustrated. Their time is valued and the BPO unit has to respect that. That is exactly what happens when you hire technicians as customer service personnel. They resolve the issue immediately, making the caller realize that your phone answering desk is efficient and capable of attending to complicated issues. Clients want this sort of a professional behavior at the inbound call center desk. Call center units, on their part, pay a higher salary to these technicians and get them onboard.
In the present day, you cannot afford to send your call center agents to training sessions and conferences that often. There are travel and other expenses to be borne. That is why more call centers are relying on in-house training facilities to help them get equipped with what is expected of them. Training modules can be project-specific or just call center services in general. When you hire fresh grads, you will need to put them under some generalized BPO training to bring them to the industry standards. No matter what kind of education they have received, working on a regular call center floor is a different experience altogether.

Very recently, the FTC had slotted advisors and counselors under the telemarketing laws. If they call their clients at times of the day when the telemarketing services law prohibits them, they will be fined. Moreover, the FTC also made it clear that call center agents cannot ask the customers to pay for services that they have not rendered. This is particularly true for the debt recovery BPO agents. They demand payment even before the customer has been relieved of his debt. Their fake call center services add to the debt of the customer instead of relieving him! The question about the politicians calling for votes has been part of the American electoral process for decades.
