This next step may be dependent on your specific phone. Some users with basic phones can start by finding the Phone icon on the main screen of their device. Tap it, and if necessary, open up the dial pad by tapping its icon. Once you do, press and hold the 1 key until you’re connected.
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/.

Choose words and expressions that complement your business, brand and industry. As an example, a construction company would use words and expressions that convey high quality and solid workmanship; while a florist would use sensory descriptions that arouse smell and beauty.
People have short attention spans these days, and you should always craft your communications for the lowest common denominator with something as universal as your voicemail.
