1. Android 6.0 and above includes a OMTP VVM client, which (when provided with the correctconfiguration) will connect to Carrier VVM servers and populate visualvoicemail messages within the Android Open Source Project (AOSP) Dialer. The VVM client: 1. Handles the SMS messages used to activate/deactivate/query status of theservice and the SMS messages used to notify the device of events in thesubscriber's mailbox 2. Syncs the mailbox with the IMAP server 3. Downloads the voicemails when the user chooses to listen to them 4. Fetches voicemail transcriptions 5. Fetches details of voicemail quota (total mailbox size and occupied size) 6. Integrates into the Dialer for user functionality such as calling back, viewingunread messages, deleting messages, etc.
Sometimes, when the phone is not picked, the caller is automatically redirected to the voice mail. That means that when someone calls you, he or she will hear some dial tones before going to the voice mail where they could record their message. In Verizon, you can actually set the number of rings before voicemail.

Now, click on the “Settings” or “More Settings” option. Remember that if you don’t have this option, then this method will not work for disabling Voicemail.Scroll and check for the “Call-forwarding” and tap on it.You may be asked to choose from “Voice Call” and “Video Call” forwarding settings. Choose the Voice Call option.Disable call-forwarding and save the settings if your device asks. You have disabled Voicemail now.
On the other hand, a stellar professional voicemail is more than just a way to ensure callers are heard. It’s actually a gateway to encourage recruiters, clients, connections, venders, and other callers to continue forward with the first step in developing a business relationship, which is them making contact. The power of the right voicemail greeting is the caller actually staying on the line to leave that contact information or gain access to an alternative contact point.
