### Extension Details

Each extension allows you to control how incoming calls are routed and how callers reach a specific destination in your call flow.

Start by selecting a **Key from the dropdown menu** to assign which **Key callers will press on their keypad** to reach that extension (for example, pressing **4** for Sales or **5** for Support). Each key corresponds to a menu option in your phone system.

After selecting the key, enter a **Label** to name the extension (such as *Main Extension*, *Sales*, or *Support*).

Next, choose a **Forwarding Method** under **Select Forwarding Method**. Available options include **Standard**, **Simultaneous**, **Sequential**, **Geo**, **Voicemail**, and **In-App Calling**, each determining how incoming calls will be routed.

Once the forwarding method is selected, enter the **Forwarding Number or Label**, adjust the **Ring Duration**, and configure additional settings such as **Caller ID**, **Tags**, or **Voicemail** preferences if needed.

When you are finished configuring the extension, click **Save** in the upper-right corner to apply the changes.

## Forwarding Methods Explained

800.com provides several forwarding methods that determine how incoming calls are routed for each extension.

- **Standard Forwarding**  
  Routes calls to **one forwarding number at a time**. If you add multiple numbers, you can assign a **weight** to control how often calls are sent to each number relative to the others.
- **Simultaneous Forwarding**  
  Rings **multiple forwarding numbers at the same time**. The first person to answer receives the call, which is useful when multiple team members can handle incoming calls.
- **Sequential Forwarding**  
  Routes calls through a **list of forwarding numbers in order**. If the first number does not answer, the call is forwarded to the next number in the sequence until someone answers.
- **Geo Forwarding**  
  Routes calls based on the **caller’s area code or location**. Calls from specific regions can be sent to different numbers, allowing you to direct callers to the most appropriate team or location.
- **Voicemail**  
  Sends calls **directly to voicemail** when selected. This option is commonly used for after-hours routing or when calls should not be forwarded to another number.
- **In-App Calling**  
  Routes calls directly to the **800.com web or mobile app**, allowing users to answer calls without forwarding to an external phone number.
