Hi All, Can anyone can find out what happen. We've been using the 3CX system for over 4 months and seems everything fine. Since these week, we cannot dial out couple times, we have to restart the gateway. But on the 3CX management Console doesn't seem the gateway is disconnect (stay on green). We are using the Grandstream GXW4108 gateway. Dose anyone happen before? What's wrong? Thank you.
