- Open a web browser on a computer connected to the same network.
- Enter the IP address of the base station into the browser's address bar and press Enter.
- Log in using the default administrator credentials (refer to the Quick Start Guide for default username and password).
- Follow the on-screen prompts to configure network settings, SIP accounts, and DECT handsets.
5. Operating the Base Station
5.1 Registering DECT Handsets
Up to 20 DECT handsets can be registered to the N670 IP Pro base station.
- On the N670 IP Pro web interface, navigate to the DECT settings and enable registration mode.
- On your DECT handset, initiate the registration process (refer to your handset's manual for specific steps).
- Enter the system PIN when prompted (default is usually 0000).
- Once registered, the handset will display the base station name or an internal number.
5.2 Making and Receiving Calls
Once handsets are registered and SIP accounts are configured, you can make and receive calls.
- Making a Call: Dial the desired number on the registered DECT handset and press the call button.
- Receiving a Call: When a call comes in, the registered handsets will ring. Press the call button to answer.
- The system supports up to 8 simultaneous calls, ensuring high operational readiness.
5.3 SRTP2 Security
The N670 IP Pro ensures call security through SRTP2 (Secure Real-time Transport Protocol). This encryption protocol protects your voice communications from eavesdropping. Ensure SRTP2 is enabled and properly configured in the web interface for all SIP accounts.
