Give each teammate one so calls can ring them, they can call out, and their voicemail is their own. The line can be a desk phone, the Hiveku mobile app, or the softphone that calls from the computer. This guide adds a desk phone at Northwind's front counter for Jamie Holloway, then shows how a desk phone gets its settings. ## Add the extension **1. Open Extensions** Click **Communications** in the left rail, then **Routing** at the top, then **Extensions**. Click **New extension**. **2. Fill in the line** Type an **Extension number** (2 to 6 digits; keep one pattern, such as 1001, 1002 and so on) and a **Display name**. Pick the **Phone type** and, under **Assign to a person**, who the line belongs to. Click **Create extension**. ![New extension: Extension number 1061, Display name Front counter, Phone type Desk phone (Yealink, Polycom and others), Assign to a person Jamie Holloway, all outlined, and Create extension, outlined](https://mintcdn.com/locusdigital/BaedFW3Bx4Pbvdho/images/how-tos/phone/ex-01-new-extension-closeup.webp?fit=max\&auto=format\&n=BaedFW3Bx4Pbvdho\&q=85\&s=6548190a994d18308a4f0156c09ec1de) A desk phone for Jamie The phone types: * **Desk phone**: a phone on a desk, such as a Yealink, Polycom or Grandstream. * **Mobile app**: calls on the Hiveku app on their phone. * **Desktop softphone**: calls from the computer. * **Forward to another phone number**: rings an outside number, such as someone's own mobile. The new line is in the list, with its type and the person it belongs to. Type its number or name in the search box to find it. ![The extension 1061, Front counter, Desk phone, Jamie Holloway, outlined, with No direct number, Account default number as the outbound caller ID, Not registered and Offline](https://mintcdn.com/locusdigital/BaedFW3Bx4Pbvdho/images/how-tos/phone/ex-02-the-new-line-closeup.webp?fit=max\&auto=format\&n=BaedFW3Bx4Pbvdho\&q=85\&s=ce4d81abe08663d8fe0dcbc791d0af70) The new line It shows **Not registered** and **Offline** until a phone connects to it. Each person can have one extension of each phone type. If you pick a type they already have, the box says so before you create it, and **Create extension** stays off until you change the person, the type or the number. ![New extension with Desktop softphone and Jamie Holloway picked, and the message Jamie Holloway already has a desktop softphone extension (1001), and each person can have one desktop softphone extension.

Tell Hiveku which phone it is** Click the arrow at the left of the line to open it. Pick the **Phone model**, type the **MAC address** (the 12 letters and numbers on the label under the phone), and click **Save changes**. ![The 1061 Front counter line opened: Display name, Assigned to Jamie Holloway, Phone model Yealink T54W (WiFi) and MAC address, outlined, Ring timeout, SIP username 1061, Type Desk phone, and Save changes, outlined](https://mintcdn.com/locusdigital/BaedFW3Bx4Pbvdho/images/how-tos/phone/ex-04-desk-phone-closeup.webp?fit=max\&auto=format\&n=BaedFW3Bx4Pbvdho\&q=85\&s=90749d560b46ddd8643ce4bcbc180fe8) The phone's model and MAC address **2. Point the phone at Hiveku** Click **Admin** at the top, then **Provisioning**. Copy the **Zero-touch provisioning URL** with the button next to it, and paste it into the phone's **Auto Provisioning** setting (on the phone's own settings page or menu). When the phone restarts, it downloads its settings and connects itself, with no passwords to type. ![Phone provisioning: the Zero-touch provisioning URL with its copy button, outlined; Supported phones, Yealink T31P, T33G, T43U, T53W, T54W and WH62, Polycom VVX 250, 350 and 450, Grandstream GRP2602, GRP2612 and GRP2614; and Assigned phones with 1061 Front counter, outlined](https://mintcdn.com/locusdigital/BaedFW3Bx4Pbvdho/images/how-tos/phone/ex-05-provisioning-closeup.webp?fit=max\&auto=format\&n=BaedFW3Bx4Pbvdho\&q=85\&s=7678e77ee4d55d61de9d8e05517cc101) The address the phone gets its settings from **Supported phones** lists the models that set themselves up this way. Other phones may work if you type their settings in by hand. Northwind has no desk phone to plug in, so this guide stops here. Once a phone connects, its line shows the phone under **Registered on**. ## Change or remove a line Open a line with its arrow to change its name, its person or its **Ring timeout** (how many seconds it rings), then click **Save changes**. **Voicemail settings** sets up its voicemail box, and the **Outbound caller ID** column picks which of your numbers shows when the person calls out (see [Choose the Number and Name People See When You Call](https://docs.hiveku.com/how-tos/phone/caller-id.md)). To remove a line, click the trash icon at the end of its row. Hiveku asks first, because the phone on that line stops working within a minute. ## Good to know * **Make calls reach the line.** Send a number to it, or add it to a group: see [Choose Where Calls to Your Number Ring](https://docs.hiveku.com/how-tos/phone/choose-where-calls-ring.md), [Ring Several People at Once](https://docs.hiveku.com/how-tos/phone/ring-group.md) and [Hold Callers in a Queue Until Someone Is Free](https://docs.hiveku.com/how-tos/phone/call-queue.md). * **Old app lines.** When someone reinstalls the Hiveku app or changes phones, the old phone's line stays in the list and can still ring in groups. Delete it with the trash icon. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
