Press 1 is really only worth it if you can get a "specialized" list and target those business owners based on the relationship. For example, if somehow you got a list with all of Time Warner Cable's Business Class customers, dumped them into the dialer and the recording started "Attention Time Warner Cable's Business Class customers, for a limited time..." Other than that you will continue to experience those issues. Also, a few hundred will be burned through in minutes. You typically need to run through thousands of them at a time. When they say something is a numbers game, press 1 is absolutely a numbers game. Timing is also very important with these. God have mercy on your soul if you try running a press 1 campaign all with restaurants during lunch.
