Voicemail Number: This will be used as a unique identifier for your mailbox. The minimum is adding one digit to up to ten digits, for example you can set 1 or 5432897. NOTE: The number cannot be set to 0. If you have your mailbox to 0 it's suggested to change to a different value to prevent issues with the voicemail service.
Of course, we want to know as soon as an incoming voicemail is saved, so again, it’s Twilio to the rescue. By adding a few lines of code to our Python script, Stacey and I each get an SMS notification telling us there’s a new message. Note that Twilio’s API requires a separate call for each message to be sent, which is why the similar code repeats once for Stacey’s phone number and then again for mine. If you plan to send bulk messages from Twilio, I expect that you can build a list of phone numbers and loop through them with the API call. Since we only have two contact numbers and don’t expect to add any more, I decided not to loop through a list of two elements.

Any Cisco Jabber calls you can't answer gets sent to voicemail so the person can leave a message. To set up voicemail, you'll need to get your voicemail account information from your administrator.
Example 1. Hi, you’ve reached [your name]. Thanks for calling. I can’t answer your call at the moment, however if you leave your name, number and message, I’ll get back to you as soon I can. There’s nothing wrong with this classic style of voicemail greeting. It’s short, sharp, and to the point.
