If you’ve already created a custom voicemail on your iPhone, you can tap Play to see how your voicemail sounds. If you’re interested in creating a new message, tap the Custom button. From here, you can start recording your message by tapping Record and tapping Stop whenever you’re finished. Once you’re finished recording, tap on Play to make sure the message comes across as you’d like and hit Save (in the upper right) to save it as your voicemail.
5. Holiday Voicemail Greetings. Happy [X holiday]! You've reached [your name] at [X company]. I am currently out of the office, but please leave me your name, phone number, and the reason you are calling, and I’ll return your call after the holidays.

9.) Bienvenido/a a John Doe. Lo sentimos, en estos momentos no hay nadie en nuestras oficinas. Por favor, déjenos un mensaje con su nombre y número de teléfono tras escuchar la señal. Le devolveremos la llamada tan pronto como sea posible.
Ive been saving my grandmothers voicemails for almost 8 years now and when i went to upgrade my phone, i almost fainted when the rep told me they were going to be erased. Thanksfully he put us in touch with a company called http://www.voicemailsforever.com and they ended up much cheaper than the one you suggested above. i think your readers would benefit because they do it for so much less.
