If you want to add another condition to your rule, select Add condition. You can add multiple conditions to a rule but do this judiciously so your rules don't become overly complex.
But the questions you ask in a voicemail should be so specific that they could never be intended for another listener. For example, if I was selling financial management technology, I might ask the voicemail recipient which financial software they use today, or if all of the company's financial analysts work out of the central office.

An alltime classic technique was offered by Thomas J. Elijah, III, of Elijah & Co. Real Estate, at a SalesMasters meeting. He said to leave a partial message that includes your name and phone number, then pretend to get cut off in midsentence, as you’re getting to the important part of the message. “Cut it off in midword,” Elijah says, “it works like a charm because the prospect can’t stand not knowing the rest of the information, or thinks his voice mail is broken.”
Friends and colleagues speak to each using first names only. So do people of authority. They do not call each other and leave voicemail messages asking for Mister, Miss, or Mrs. Therefore, when you call a person you want to do business with and you leave a voicemail message, refer to them by their first name only. Don't say mister, miss, or misses. Don't say their last name. Begin your voicemail message by saying only "hi/hello" followed by the person's first name. Or, you can even forget the "hi/hello" and just say the person's first name. That is how you show confidence and authority and separate yourself from weak salespeople.
