Call Waiting
At Vonage, Call Waiting isnt just a beep during your call. Combined with Caller ID with Name, you can decide if you should put your call on hold and answer it.
Do Not Disturb
When Do Not Disturb is on, all your incoming calls are automatically sent to Vonage Voicemail Plus®. If you havent enabled Voicemail Plus, all incoming calls will be sent to a system message indicating that you are not accepting calls at this time. You can turn Do Not Disturb on or off for each of your Vonage lines separately. And Do Not Disturb wont affect your outgoing calls.
Repeat Dialing
When you get a busy signal, just press #5 and at the tone, hang up. The number you are trying to reach is automatically redialed for up to 30 minutes. When the number isnt busy anymore your phone rings – you just pick up the phone and then wait for your party to answer the call.
Voicemail Plus
Vonage provides you with the ability to access your voicemails whenever, wherever, and however you choose. With Voicemail Plus, you can access your voicemail from any phone, from your Online Account, through your email.
