Hi Roman, and welcome to OBi-land.
Yes, the OBi 2xx series ATAs and 1000 series IP phones (with USB WiFi dongles or built in WiFi) can store up to 20 saved access point credentials (SSID and password). You can also select one of them as the preferred access point. If the preferred AP isn't available, the OBi will connect to one of your saved APs, if it finds it when it scans for available APs.
For example, you may spend most of your time at the office, and connect to the AP there. If you also want to use the device at home, then store your home's WiFi AP credentials, and when you're at home, it'll connect accordingly.
