Hello. Haven't been here in a while ( I tried to contribute a couple of times but we've been super swamped ) I hope you haven't missed me I've been putting up with the fact that I need to mute my headset when not talking in order to prevent surrounding noises from chopping the caller's voice. I couldn't find a setting to help with that so I've been sucking it up. Now, what's making me think about getting a different set-up is that at least once or twice a day phone calls get cut off for no reason. We have a MJ line and a "voip" coming out of the comcast modem. It happens to both lines, inbound and outbound. Comcast checked the connection and gave us a new modem Used the lines for while without the Gateway and there were no cut-offs. Ran the self tests multiple times Changed ports Not doing any other operation on either PC Reinstalled the 3cx software No incoming calls arrive when this happens Basically we can't see any reason for this problem. Suggestions, before I give up on grandstream 4104 and 3cx soft phones? If you also have a suggestion on the room sound chopping up the caller's voice it would be much appreciated. Thank you as usual!
