Dear recruiters, if you prefer telephone calls, why not also learn how to leave a message on a voicebox, display a caller ID, and list your phone number on some legit page on the internet?

Otherwise you'll leave the impression of a desperate outbound call center agent paid not by leads and conversions but just by the quantity of calls made during the day. If I had such a job, I'd also call voiceboxes and busy developers all day and get money for listening to signals tones before hanging up.
