Voice mail allows business professionals access to messages -- even when they're away from the office. A call to any business or home used to mean one of three things -- an answer, a busy signal or endless, unanswered ringing. Increasingly, it now means an encounter with voice mail.
The right way to leave your phone number is to start saying your phone number with your area code and then take a 2-3 second pause while the person listening to your voicemail message gets a pen and paper. Then, continue with the next 3 digits, make another 2 second pause, and then say the last 4 digits. Then, slowly repeat your phone number again.

check words for the English /oʊ/ vowel. Many non-native speakers make this more like a single vowel and it’s a double vowel so it should have /o/ and /ʊ/ smoothly joined together. Check it in the word ‘phone’ . Another double vowel to look out for in your Voicemail Greeting example is the diphthong vowel /eɪ/. This vowel is in words like ‘wait’ and ‘able’. Many people use the word ‘can’t’ in their Voicemail greeting example. This can be a trap for non-native English speakers. That’s why we chose ‘unable’ instead! Watch out for the word ‘can’t’! In American English and British English the vowel in ‘can’t’ is pronounced with the vowel /æ/ like in ‘pat’ – /kænt/.
