## Reviewing Number Settings

For a full list of your numbers, you can click “Numbers” on the left-side menu and view all of your numbers together, regardless of their location on your system. You can click the settings (Cogwheel) on the right to edit settings for a given number.

### 1. Caller-ID

Your Caller ID Name can appear when making outbound calls, and has a maximum character limit of 15. You can also turn on the Inbound Caller ID to allow you to see what a caller dialing in to speak with you has set as theirs

Please note that caller ID name (CNAM) is a best effort feature. Databases for CNAM are not usually shared amongst different carriers, although there are steps our support team can take in order to help improve it’s accuracy. Reach out to us at [experience@virtualpbx.com](mailto:experience@virtualpbx.com) or calling +1 (888) 825-0800 once completing the above steps for additional support.

### 2. e911

Complete this section that will appear for the 911 emergency services, in case you need to dial it from your device. This will alert the authorities to this number’s location when called from any of your VirtualPBX VoIP devices.

### 3. Prepend

Help your Users identify which number the caller has dialed when answering from one of the VoIP devices. This info, which can include departmental identifiers (Sales, Team A, etc.), displays at the beginning of the caller’s ID when the delivered to the Softphone, Web Phone or desk phone.

### 4. Sync

In the extremely rare case Dash displays your numbers incorrectly, we’ll use this step to troubleshoot the inaccuracy. This will help align your number with your account.

## Deleting a Number

When a number is no longer necessary, you can Un-assign it to move it to your Spare Numbers. You’ll find a red un-assign button wherever it’s located (Main Number, User, Group, etc). At this point, it’s not yet fully deleted and can still affecting your pricing.

To follow through on fully deleting, head to the Numbers tab on the left-side menu and click Spare Numbers at the top to display the un-assigned number.

To fully remove the number from the Dash account, click the box next to the phone number, which will reveal the option to Delete in the section above.
