# Internal and external dialing

> Dial a short extension to reach a coworker, or a full number to call outside your organization.

How you dial depends on who you're calling. Reach a coworker by their extension, and call anyone outside your organization by their full phone number.

## Call a coworker (internal)

To reach someone on your account, dial their **extension** — the short 3–4 digit number assigned to their line. You can also open **Contacts**, find the person, and start the call from there. A colored dot shows their current state:

* **Green** — their phone is ringing.
* **Blue** — they are on a call.
* **Idle** — they are free.

## Call an outside number (external)

To call someone outside your organization, dial the **full phone number**. If your account has **7-digit dialing** turned on, you can dial local numbers without the area code; otherwise, enter the complete number.

## Send digits into a menu

If you reach an auto attendant or phone menu, open the dial pad mid-call (the blue arrow icon pointing right) to enter your selection. See [Softphone](/omnia/user-guide/softphone) for the full set of in-call controls.

Contact support if a coworker's extension or an outside number won't connect after you've confirmed the digits are correct.
