Attenzione - per uso linea analogica serve la scheda aggiuntiva. Ottimo software, personale di Yeastar in Cina molto disponibili via Chat per aiutare con il settaggio. Ottima la app Linkus per usare il telefono in remoto. Attenzione - seguire i video tutorial su YouTube per installazione alcuni passaggi non sono scontati..
