The Features of Vonage Phone Service

As Vonage phone service is Internet based, that is, it uses voice over Internet protocol (VoIP), it comes packed with useful features. This is thanks to the advancement of today's technology. here you can learn more about Features of VoIP.

The Features of Vonage Phone Service

Here is the table showing the list of all Vonage phone service features:

(P) besides a feature means there is an additional cost. All the prices are listed below together within feature explanations. For some features, prices depend on the calling plan you have, so we can't tell the exact price. You can see that inside your Vonage account.

Now we go into explaining each of the listed features, one by one.

 

Add a Line (Add a Voice Line)

You can add a second voice line to your Vonage service through your Online Account. The cost for your additional line depends on the calling plan that you choose and will be calculated before you confirm your order.

You cannot add an additional line if any of the following is true:

• You are a new customer and your adapter has not yet been configured and shipped.
• You currently have a pending order for an additional line that has not yet completed.
• Your account is in Suspend status or has been disconnected.

 

Anonymous Call Block

The Anonymous Call Block feature prevents callers who do not display their phone number on your Caller ID from ringing your Vonage phone number. Instead of ringing your phone, these callers will hear a message informing them that their call cannot be completed until their Caller ID is unblocked. In other words, anyone who dials you with a blocked Caller ID will receive a message that you don’t answer calls from unknown numbers. Callers who block their Caller ID get stopped from ringing your phone.

Anonymous Call Block stops incoming calls from the following only:

• Anonymous
• Private
• Private Number
• Private Name
• Number Private
• Caller Private
• Restricted
• Withheld

By default, Anonymous Call Block is turned off. Callers who do not block their number are able to ring your phone and this includes Caller ID displays that show Unavailable.

 

Bandwidth Saver®

This feature helps you maintain great call quality even with poor Internet connections. Vonage uses 90 kbps of bandwidth during a call and this is sufficient for most calls. If you have limited  bandwidth available, 90 kbps may cause sound problems. Adjusting the amount of bandwidth used by a call can resolve sound issues. This is when Bandwidth Saver® kicks in.

Bandwidth is the amount of data that can be carried across a network in a given time period. The higher your bandwidth, the more data you can send and receive. Every device connected to your network, including your Vonage adapter, uses your bandwidth when sending or receiving information.

Adjusting your bandwidth can sometimes increase the audio quality of your calls. You can change the default bandwidth setting for Vonage calls with the Bandwidth Saver tool. It is located on the Adapter & 911 Settings tab of the Features & Settings section of your Online Account.

Steps to change the Bandwidth Saver settings in your account:

1. Sign in to your Online Account.
2. Click the Summary tab and, under My Numbers, select a phone number.
3. Go to Features & Settings and select Adapter & 911 Settings.
4. Go to Telephone Adapter and click Bandwidth Saver.
5. Select your bandwidth, which has three settings:
   • Highest available sound quality (90kbps)
   • Higher than normal sound quality (50kbps)
   • Normal sound quality (30kbps)
6. Click Save.

If you want to check your Internet speed, use our Test Internet Speed Tool.

 

Call Filter

Vonage Call Filter feature allows you to filter unwanted calls. You can screen and block annoying spam calls with Spam Block. You can also block up to 500 numbers with Selective Call Block. In your online account, select one of the following:

1. Block all incoming calls marked as SPAM
2. Direct all incoming calls marked as SPAM to voicemail
3. Continue to receive all incoming calls marked as SPAM.

Selection can be easily changed or undone.

Block up to 500 numbers
With Selective Call Block, future incoming calls from the blocked number will not appear in either Call Activity or Recents.

Use your Vonage Extensions app to easily block a number. You can also log in to your online account and block numbers in your recent activity or by manually entering the number.

You can unblock numbers in your Vonage Extensions app, or by logging in to your online account.

Call Hunt

Use the Call Hunt feature to forward incoming calls through a specified sequence of up to five phone numbers when a busy signal is encountered. All the phone numbers must be on the same Vonage account.

When a phone is busy, an incoming call is forwarded to the next phone number in the ring sequence. This continues until a phone number is not busy or the ring sequence ends. If the call is unanswered or the ring sequence ends, the call uses the Voicemail option you specified for that number.

Once you set a Call Hunt ring sequence in Online Account, you do not need to do so again unless you want to change the numbers in the list. Instead, turn on or off as needed.

NOTE: You must have two or more phone numbers on the same Vonage account to use this feature.

Call Hunt Setup

Set up your Call Hunt ring sequence and incoming calls will forward to the next Vonage number on the list when that line is busy. You can also select which phone number's Voicemail will answer if all lines are busy. You must have more than one voice line on the same Vonage account to use Call Hunt.

NOTE: Any Vonage phone number using the Extensions App with inbound calling enabled cannot be used in a Call Hunt sequence.

Call Waiting

Vonage Call Waiting lets you see who's calling when you’re on the other line. With this feature, you can place your current call on hold to pick up an incoming call or you can choose to let the incoming call go to voicemail. A tone while on a call alerts you that there is an incoming call.

Call Waiting is turned on by default, but you can turn it off for a single call or turn it on and off through your Online Account. Turning off prevents you from picking up another call while you are on a call.

 

Caller ID

As with most other Vonage features, the Caller ID feature is free, that is, it is included with your Vonage phone service. It allows you to see who is calling before you pick up the phone. Caller ID with Name displays the name and telephone number (if available) for incoming calls on any Caller ID enabled device or telephone. For calls that you place from a Vonage U.S. residential telephone number, your name and telephone number are displayed, if this feature is supported by the service of the person you are calling.

The display of your name and telephone number is turned on automatically with your Vonage service. The name that you provide when you sign up for Vonage service is the name that is displayed when you place a call.

Vonage Caller ID (as well as most in the industry) has a 13 character limit for the display. Both your last name and the initial of your first name are displayed when you place a call, if your name is less than 13 characters in length.

 

Caller ID Block
