To display the **Numbers** page, from the Voiso navigation bar, select **Inbound > Numbers**. The **Numbers** page contains three main functionality areas: [Numbers](/v1/docs/inbound-inbound-numbers#numbers) [Buy numbers](/v1/docs/inbound-inbound-numbers#buy-numbers) [Add numbers](/v1/docs/inbound-inbound-numbers#2-add-thirdparty-number) (single or bulk) ![Inbound Numbers Default Page](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20Default%20View.png) ## Numbers The **Numbers** page allows you to view and manage your numbers. The table includes the following columns: | Column | Description | | --- | --- | | Number | The phone number in E.164 format. | | Added on | The date that the number was added to your contact center. | | Label | A label that you specify by [editing the details](/v1/docs/inbound-inbound-numbers#4-number-details) of the number. If you do not provide a label, then **Not assigned** is displayed. | | Country | The name and flag of the country to which the number belongs. | | City / Type | The phone number type: **Geographic**, **National**, **Toll-free**, **Shared-cost**, **Mobile**, and others. If the number type is **Geographic**, then the locality to which it belongs is displayed – for example, Los Angeles, CA. | | In use | Indicates whether the number is assigned to a flow, Caller ID, or CID group. Numbers that have been automatically replaced by the [ASR performance optimization](/v1/docs/asr-performance-optimization) feature will have a warning icon next to them so you know they are no longer in use as a Caller ID in Dialer campaigns and Caller ID groups for manual and click-to-call dialing. | | Action icons | Click an icon to add the number to a [CID group](/v1/docs/outbound-cid-groups), add the number to a [flow](/v1/docs/inbound-flows#assigned-numbers), or [delete](/v1/docs/inbound-inbound-numbers#7-delete-number) the number. | The functions available on the **Numbers** page are described in the following sections (1-9). ![Inbound My Numbers Page](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20My%20Numbers%20View.png) The **Buy numbers** feature is described in the [next section](/v1/docs/inbound-inbound-numbers#buy-numbers). 1. [Search](/v1/docs/inbound-inbound-numbers#1-search) 2. [Add numbers](/v1/docs/inbound-inbound-numbers#2-add-numbers) 3. [Select all](/v1/docs/inbound-inbound-numbers#3-select-all) 4.

Important Numbers with a yellow alert icon have been replaced and are no longer in use as a Caller ID. When there are no condidate replacement numbers remaining in your inventory, the number requiring replacement is marked with a red alert icon. Refer to [ASR performance optimization](/v1/docs/asr-performance-optimization) for more information about this feature. ### Restricted numbers In some countries and regions, telecom regulations require extra verification before certain phone numbers may be used. When you purchase a number that is classified as **restricted**, the provider must review and approve supporting documents before Voiso can activate the number for Caller ID or inbound calling. Because this approval happens outside of Voiso, restricted numbers may not work immediately after purchase. Voiso shows a red restricted indicator on the **Numbers** page to let you know that the number is awaiting document submission or validation. Once the provider approves the documents, Voiso automatically enables the number for use. ![Inbound Numbers Restricted Numbers](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20Restricted%20Numbers.png) Contact your Voiso account manager or support@voiso.com for help with submitting documents. Tip Restricted status depends on local jurisdiction and number type. Approval time varies by provider and country. ### 1. Search To search through all of your numbers to find a specific number or set of numbers, enter at least two digits in the **Search** field. The search results include all numbers that *contain* the number string you entered. You can search by the following parameters: | Parameter | Description | | --- | --- | | Country | The name of the country to which the number belongs. | | Type | The phone number type: **Geographic**, **National**, **Toll-free**, **Shared-cost**, **Mobile**, and others. If the number type is **Geographic**, then the locality to which it belongs is displayed – for example, Los Angeles, CA. | | Label | User defined labels when the number is purchased. | Sort the results by **In use** to find numbers with **Yes**. Click an in-use number to determine whether it is assigned to a [User](/v1/docs/users-users) as the default Caller ID, in a [flow](/v1/docs/inbound-flows) as an entry point, or is in an outbound [Caller ID (CID) group](/v1/docs/outbound-cid-groups). ### 2.

To buy new numbers for your contact center, from the Voiso navigation bar, navigate to **Inbound > Numbers**, then click **Buy numbers**. ## Buy numbers page When you click **Buy numbers**, the **Buy numbers** page is displayed. The **Select country** panel contains an alphabetically sorted list of the countries that are available for your contact center. If you need to add more countries to the **Country** page, click **Contact us** at the bottom of the page or contact your Voiso account manager or support team directly. To begin the purchase process, select a country for which you want to buy numbers. ![Inbound Numbers Buy Numbers Tab Country Page](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20Buy%20Numbers%20Tab%20Country%20View.png) Different options are displayed after you select a country, depending on the availability of numbers within that country and the types of numbers that are available for your contact center. The following tabs might be displayed after you select a country: | Number Type | Description | | --- | --- | | Geographic | A city, state, or region within the selected country. | | National | A country-wide number. | | Toll-free | A toll-free phone number, or freephone number in some countries, is billed to you rather than the calling party. Toll-free numbers enable contacts to call you without incurring long-distance phone charges. Toll-free numbers begin with a special dialing prefix, such as **800**. | | Mobile | A mobile phone number. | | Shared-cost | A shared-cost number is partially billed to you and partially to the contact, enabling the contact to make a call to another country, but pay only the maximum rate for calls within their country. | ## Buying numbers for a country After selecting a country, click the tab with the number type in that country that you need, then select a phone number from the list of numbers. The following section demonstrates selecting a Geographic number. The process is similar for other number types. ### Geographic number type example After selecting a country, in the **Geographic** number type panel, select a geographic region, such as a city. In the screenshot for the Netherlands, several cities and regions are listed. Next to each city or region name is the number of phone numbers available to buy for the geographic region. Use the **Search** field to find a specific city or region. ![Inbound Numbers Country Geographic Type Tab](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20%20Country%20Geographic%20Type%20Tab.png) If the city of **Amsterdam** is selected, a table of phone numbers is displayed, along with their activation fee, monthly fee, and price per minute. ![Inbound Numbers Geographic Type Tab City Numbers](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20Geographic%20Type%20Tab%20City%20Numbers.png) Use the **Search** field to look for a specific number string. When you select one or more numbers, the activation, current month, and monthly fees for the numbers are totaled at the bottom of the page. ![Inbound Numbers Geographic Type Tab City Numbers Selected](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20Geographic%20Type%20Tab%20City%20Numbers%20Selected.png) Click **Buy numbers** and follow the on-screen instructions to complete payment and add the numbers to your **Numbers** page. Tip The numbers do not appear immediately in the **Numbers** page. You have to wait a few minutes for them to be processed and assigned to your contact center. ## Minimum service term Some numbers available to buy have a minimum service commitment (for example, 6 months). Some minimum service commitment numbers include an early return fee equal to the remaining months of the term because Voiso must pay the carrier for the full term. Minimum service term numbers are clearly indicated in a transparent and understandable format whether you are browsing, purchasing, managing, or returning numbers. ### Browsing minimum service term numbers When you are using the **Buy numbers** view to browse available numbers, numbers with a minimum service term include the number of months that must be purchased for the number in the **Minimum service term** column. Returning (deleting) these numbers prior to the end of the service term will result in your account being immediately charged for the balance of the term. ![Inbound Numbers Buy Numbers Minimum Service Term](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20Buy%20Numbers%20Minimum%20Service%20Term.png) ### Purchase confirmation If you select a number for purchase that has a minimum service term, after you click **Buy numbers**, a confirmation dialog box is displayed to you asking you to confirm that you understand the terms of the purchase of a minimum service term number. Click the checkbox to indicate that you agree to the service terms, then click **Buy numbers** to proceed with the transaction. If you do not wish to purchase the minimum service term number, click **Cancel** to be returned to the **Buy numbers** page and deselect the numbers that have a minimum service term before proceeding with your purchase of other numbers. ### Reviewing your purchased numbers The **Numbers** page allows you to filter your numbers by their status, including numbers that have a minimum service term. Click the **Select status or statuses** menu, then select the **Minimum service term** option. Click a number to view its properties in the number details panel. You can view how many months remain in your service term in the **Pricing** section. Numbers with a remaining service term will indicate the number of months remaining. When the term is complete, the minimum service term is no longer displayed. [Video](https://cdn.document360.io/44ae307a-3737-4fbf-98e0-9b888deb90dc/Images/Documentation/Inbound%20Numbers%20Filter%20and%20View%20Minimum%20Service%20Term%20Numbers.mp4) ### Early return (deleting a number) If you [delete](/v1/docs/inbound-inbound-numbers#7-delete-number) a minimum service term number before the end of the term, the following confirmation message is displayed: ``` This number has a minimum service term. If you delete it now, your account will be charged immediately for the remaining months: $x.xx ``` Click **Delete** to return the number or **Cancel** to keep using the number. ### Post term return (deleting a number) If you [delete](/v1/docs/inbound-inbound-numbers#7-delete-number) a minimum service term number after the end of the term, the number is returned with no additional fee applied. An international standard that specifies the format for phone numbers. In E.164 format, a phone number consists of a country code, a national destination code, and a subscriber number. The E.164 format eliminates additional characters or symbols like parentheses, dashes, or spaces, providing a globally recognized structure for telephone numbers. Refer to https://www.itu.int/rec/T-REC-E.164 CID. The identification phone number used for an outbound call. The number that is displayed to the call recipient. CIDs might become flagged by phone network providers if they are reported as SPAM or fraudulent. Caller ID. The identification phone number used for an outbound call. The number that is displayed to the call recipient. CIDs might become flagged by phone network providers if they are reported as SPAM or fraudulent. The name part of a website address (URL). Domain names identify Internet resources, such as computers, networks, and services, with a text-based label that is easier to memorize than the IP Address. In your Voiso contact center, the domain is the '.voiso.com' part of the URL. A SIP URI (Session Initiation Protocol Uniform Resource Identifier) is a unique address to locate and communicate with endpoints in a SIP-based contact center. It is similar to a URL (Uniform Resource Locator) used on the world wide web. SIP URIs allow SIP endpoints to locate and connect with each other. A complete SIP URI looks similar to an email address, with the user part followed by the at symbol "@" and the domain part. For example, "alice@example.com" or "+15551234567@sip.provider.com" Comma-Separated Values. A data file format where the content is structured in tabular form. Fields (data values) are separated by commas. Rows (records) are separated by line feeds. Voiso supports UTF-8 format for CSV files. CSV files allow interchange of data between spreadsheet applications, text files, and database. It is a common format for importing and exporting data. Each row represents a record. Each value represents an attribute. ## Related - [Caller ID groups](/outbound-cid-groups.md) - [Flows](/inbound-flows.md) - [Users](/users-users.md) - [Inbound calls](/agent-panel-inbound-calls.md) - [How to start receiving calls](/how-to-start-receiving-calls.md)
