You have just enabled web access configuration for your device.
Next we will acquire the IP address of your device, if you haven't already done so. You can acquire the IP of your device by:
Picking up the connected handset and dialing *** and then dialing 1
You should be provided with the current IP address of your OBihai device. If your IP is 0.0.0.0 please make sure that your device is properly connected to your network.
Once you have acquired your IP login to your device by using
http://DEVICE_IP/. If this is your first time logging into your device you may be asked to enter a username and password. By default for admin login this should be:
User: admin
Password: admin
If you do not have this information then you will need to either reset or acquire this login information. Unfortunately we would not be able to provide support on this topic. You may however visit the OBihai support page for your specific device.
