I would advise against using a call centers dialing software but insist on them using yours (dialer). Essentially you give up control of how your data / leads are protected. On your system you can remove the leads once converted, it will help significantly in not having your leads resold to another lead buyer.

You also want to make sure you are TCPA / DNC compliant if you plan on doing mass outbound calls, there are tons of professional plaintiffs that set out traps for companies to make a mistake on.

john is 100% correct it also lets you know exactly what is happening and that nothing is fudged on their end
