Hello, this is Joan Tracy. I’m out of the office until Tuesday, May 23rd. I’ll be sure to return your call when I get back to the office, however, if you need immediate assistance, please call my colleague Sue at 444-444-4444. Thank you.
Perhaps the biggest mistake in a sales voicemail is pitching too aggressively. If you sound like a smarmy used car salesperson, your prospects are going to delete your voicemails faster than you can say "lowest price guaranteed!"

In Australian English it’s pronounced with the vowel /a:/ like in ‘part’. Problems arise when people use the /ʌ/ vowel (like in ‘up’) instead of /æ/ or /a:/. If you do this is will sound like the worst swear word in English. Many non-native speakers often pronounce the vowel /æ/ more like /ʌ/ because they don’t have a vowel like /æ/ in their first language. Many speakers of European languages will do this (Spanish speakers and Italian speakers) and also speakers of Japanese and Korean. This problem with /æ/ also means that if you say the word ‘back’ in your voicemail greeting sample, you are likely to pronounce it more like ‘buck’. remember to pronounce word endings in English. Check you aren’t dropping any endings off or mispronouncing them.
I always end voicemails with my phone number. The reasoning? First, it's his cue to wrap up. It keeps him from rambling and gives the prospect a clear call to action: Call him back.
