Set **SIP server** to `sip.sautikit.com:5080`, **Domain** to `sip.sautikit.com`, **Username** and **Login** to your generated username, **Password** to the generated password, and **Transport** to UDP. Save, and MicroSIP registers and can make and take calls on that number from your Windows PC. ## What you need - **A Sautikit number.** KES 116 a month including VAT, no setup fee, live in seconds from the console or the API. Inbound calls are free; outbound calls cost KES 3.00 a minute, billed per second. - **MicroSIP** installed on a Windows PC, from [microsip.org](https://www.microsip.org/downloads). - **A headset** or a microphone and speakers. ## Get your SIP details from Sautikit In the [Sautikit console](https://app.sautikit.com), open **Numbers**, pick the number, go to the **SIP & Devices** tab and click **+ Add device**. Label it with the PC or person, for example "Wanjiku laptop". Sautikit shows you: | Detail | Value | |---|---| | Server | `sip.sautikit.com` | | Port | `5080` | | Transport | UDP | | Username | generated, for example `ep3f9a1c2b4d5e6f7a8b9c` | | Password | generated | If you lose the password, click **SIP setup** on the device's row to see the details again. The API creates the same credential. The response carries `username`, `password`, `host`, `port`, `transport` and `realm`: ```bash curl -s -X POST "https://api.sautikit.com/v1/numbers/$NUMBER_ID/sip-credentials" \ -H "Authorization: Bearer $SAUTIKIT_API_KEY" \ -H "Content-Type: application/json" \ -d '{"label": "Wanjiku laptop"}' ``` ## MicroSIP settings | MicroSIP field | Value | |---|---| | SIP server | `sip.sautikit.com:5080` | | SIP proxy | leave empty | | Username | your generated username | | Domain | `sip.sautikit.com` | | Login | your generated username (the same value) | | Password | your generated password | | Display name | your name or your business name | | Transport | UDP | The `:5080` at the end of **SIP server** is the part people miss. Without a port, SIP apps use 5060, and Sautikit listens on **5080**. If MicroSIP will not register, check this first. MicroSIP's documentation says the **Login** field falls back to **Username** when it is empty, so you can leave it blank. Filling it in with the same value does no harm. ## Steps in MicroSIP 1. Open MicroSIP and open its main menu. 2. Choose **Add Account**. 3. Fill in **SIP server**, **Username**, **Domain**, **Login**, **Password** and **Display name** from the table above. Leave **SIP proxy** empty. 4. Set **Transport** to **UDP**. MicroSIP's own documentation calls UDP "the failsafe value". 5. Leave the other settings (**Media encryption**, **Public address**, **ICE** and the rest) at their defaults. 6. Save the account. MicroSIP registers straight away and shows the account's status in the main window. If it shows an error instead, go to [Troubleshooting](#troubleshooting). If Windows Firewall asks whether MicroSIP may use the network, allow it on the networks you will call from. Without it, calls can ring but carry no audio. ## Make a test call Type your own mobile number in full international format, for example `+254712345678`, and press call. Your mobile should ring and show your Sautikit number. Then call the Sautikit number from your mobile: MicroSIP should ring on the PC. ## Troubleshooting **MicroSIP will not register.** Check **SIP server** is `sip.sautikit.com:5080`, not `sip.sautikit.com` alone, and **Transport** is UDP. Check **Domain** has no `sip:` prefix or port. Then check the PC is online and that an office firewall is not blocking outgoing UDP. **Registration fails with a password or authentication error.** Copy the password again: in the Sautikit console, click **SIP setup** on the device's row. Make sure there is no space at the start or end. **Username** must be the generated username, not your phone number. **It worked, then a desk phone or another PC dropped off.** Each credential is for one device. If two devices share a username, they get in each other's way and calls may not reach the one you expect. Add a separate device for each PC or phone on the number's SIP & Devices tab. **Calls connect with no sound, or one-way sound.** Allow MicroSIP through Windows Firewall, and check the router is not rewriting SIP traffic (a setting usually called SIP ALG). **Outgoing calls fail but registration is fine.** Check your Sautikit wallet has credit. Top up with M-Pesa or card from the console. ## FAQ ### Is MicroSIP free to use with Sautikit? MicroSIP is a free Windows app. On the Sautikit side you pay KES 116 a month including VAT for the number, nothing for incoming calls, and KES 3.00 a minute for outgoing calls, billed per second. ### Where do I put the port in MicroSIP? At the end of the **SIP server** field, after a colon: `sip.sautikit.com:5080`. Leave **Domain** as `sip.sautikit.com` without a port. ### Can I use MicroSIP and a desk phone on the same number? Yes. Add one device for MicroSIP and another for the desk phone under the number's SIP & Devices tab, so each has its own username and password. Each number has a device limit, shown on that tab. ### Does MicroSIP work on Mac or Android? No, MicroSIP is Windows only. On Android, iOS or Mac you can use [Zoiper](/developers/guides/zoiper-kenya-number) with the same settings, or SautiKit Phone, which needs no SIP setup. ## Skip the setup: SautiKit Phone [SautiKit Phone](/phone) is the zero-setup option: sign in and your number works, with no server, port or password to type. It runs on [Windows](https://apps.microsoft.com/detail/9mxvnklz324k), the [web](https://phone.sautikit.com) and [Android](https://play.google.com/store/apps/details?id=com.sautikit.phone), with iOS and macOS in [beta on TestFlight](https://testflight.apple.com/join/sYaGFBDv).
