Make it as easy as possible for your prospects by including your phone number near the beginning of the message, then repeating your contact information near the end for good measure.
You know that weird silent gap you hear sometimes when you get a voicemail? That one where the caller seems surprised? That’s a terrible way to start a message. Use dialing software that eliminates that awkward silence.

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.
When you answer a call, your virtual phone system will announce to you which extension the caller selected. That way, you can answer the call professionally, or send them straight to your company voicemail.
