🔧 Installation Tip

During installation and initial launch, it is recommended to keep the default settings unless you have specific technical requirements. The default parameters are optimized for most use cases.
📌 Configuring Your SIP Account

Open the Account settings window in MicroSIP and fill in the fields as follows:
- Account Name: You can enter any name (e.g., "Work") or leave it blank. This is for your reference only.
- SIP Server: sip.sipup.org
- SIP Proxy: Leave this blank. We do not use a proxy.
- Username: Enter your SIP Device Login.
❗ Note: This is not your website/dashboard login.
- Domain: sip.sipup.org
- Login: Enter the same SIP Device Login used in the Username field.
- Password: Enter your SIP Device Password (not your web dashboard password).
You can find your SIP device credentials in your control panel here:

⚠️ Important Notes
- Display Name: Leave this field empty. MicroSIP may transmit this value inconsistently.
- Caller ID: Your Caller ID is managed exclusively via the control panel, not within the softphone settings. Update it here:

📞 Dialing Prefix
The Dialing Prefix field is used for specific technical routing. Use only the prefixes provided by our service.
- Example: 002 — used for alternative US routing.
If a prefix is entered, all outgoing calls will automatically use that specific route. Remove the prefix at any time to return to standard routing.
🌐 Transport Protocol
- UDP (Default): This is the standard recommended setting for the best performance.
- TCP/TLS: If your environment requires TCP or TLS encryption, please contact our technical support first so we can enable the corresponding transport on our side.
🔊 Advanced Settings
Once the account is active, you can explore the general settings. In most cases, no changes are necessary.
| Feature | Specification |
|---|---|
| Codecs | We primarily use G.711 A-law / U-law. |
