Linphone is a free, open-source VoIP (softphone) application. Available on Windows, Mac, Linux, iOS, and Android. Below is the configuration guide for Linphone with SuperVoIP for use with Sugester.
## 1. Download and Installation
Download Linphone from the website: [linphone.org/download](https://www.linphone.org/en/download/#linphoneapp)

<table>
<tr><th>Platform</th><th>Source</th></tr>
<tr><td>Windows</td><td><a href="https://www.linphone.org/en/download/#linphoneapp">linphone.org</a></td></tr>
<tr><td>Mac</td><td><a href="https://www.linphone.org/en/download/#linphoneapp">linphone.org</a></td></tr>

<tr><td>Android</td><td><a href="https://play.google.com/store/apps/details?id=org.linphone">Google Play</a></td></tr>
</table>
Install and run the application.
## 2. Data Needed for Configuration
Before configuring, prepare the data from the SuperVoIP panel:
1. Log in to the [SuperVoIP panel](https://panel2.supervoip.pl).
2. Go to: **Virtual PBX -> Workstations**
3. Read the data for your workstation (SIP):
- **SIP Account Number** — 7-digit number (e.g., 1290245)
- **SIP Password** — password for the SIP account (**different from the login password for the panel!**)
If you do not know the SIP password — you can change it in the SuperVoIP panel by clicking on your SIP account number.
## 3. SIP Account Configuration
### Desktop (Windows / Mac / Linux)
1. Launch Linphone. The **Connection** screen will appear.
![Connection Screen](https://s3.eu-west-1.amazonaws.com/attachments.intum.net/public-files/31076/3eba990687c135a540d2848469db8c07a3bb0aa3)
2. Click the **Third-party SIP account** button.
3. A message will appear informing you that some features (group chats, video conferencing) require a Linphone account and will be hidden with a SIP account.
![Third-party SIP Warning](https://s3.eu-west-1.amazonaws.com/attachments.intum.net/public-files/31076/4d975cf9537f36b14f000a834428fcaa0b58a7b8)
Click **I understand**.
4. Fill in the SIP account form:
![Third-party SIP account Form](https://s3.eu-west-1.amazonaws.com/attachments.intum.net/public-files/31076/45fd564c0582d4188d93b0d8e172453dc9a51386)

<table>
<tr><th>Field</th><th>Value</th></tr>
<tr><td><b>Username</b></td><td>SIP account number (e.g., 1290245)</td></tr>
<tr><td><b>Password</b></td><td>SIP password from the SuperVoIP panel</td></tr>
<tr><td><b>Domain</b></td><td><code>sip.supervoip.pl</code></td></tr>
<tr><td><b>Display name</b></td><td>Your name (optional)</td></tr>
<tr><td><b>Transport</b></td><td>TCP (recommended)</td></tr>
</table>
Leave the other fields (Authentication ID, Registrar URI, Outbound SIP Proxy URI) empty.
5. Click **Connection**.
### Mobile (iOS / Android)
1. Download **Linphone** from the App Store or Google Play.
2. Launch the application and select **Third-party SIP account**.
3. Confirm the message by clicking **I understand**.
4. Fill in the same data:
- **Username**: SIP account number
- **Password**: SIP password
- **Domain**: `sip.supervoip.pl`
- **Transport**: TCP
5. Click **Connection** / **Login**.
On iOS, push notifications work automatically — incoming calls wake the application even when it is in the background.
## 4. Connection Verification
After configuration:
1. Check if Linphone shows the status **Connected** / **Registered** (green dot next to the account).
2. Make a test call — call another number.
3. Ask someone to call you — check if the ringtone works.
### Troubleshooting
If the status is **Registration failed** or **Not registered**:
- **Check the password** — the SIP password is different from the SuperVoIP panel password
- **Check the account number** — it is a 7-digit number from the workstation, not a phone number
- **Change the transport** — try UDP instead of TCP (or vice versa)
- **Firewall** — make sure ports 5060-5061 are not blocked
- **Password expired** — change the SIP password in the SuperVoIP panel and enter the new one

## 5. How It Works with Sugester?
After configuring Linphone:
1. Open the client card in Sugester.
2. Click the phone icon next to the client’s number.
