Our office is getting tired of getting calls (not all) but several times during the day during peak calling hours.. that calls get prematurely cut off. The only way to restore the call stability is hard reboot the Gateway. All feedbacks are welcome before getting a replacement Gateway. We currently have a Grandstream GXW-4104 and our office is getting busier with calls and so far this has become very unreliable for us to use. We just have 2 PSTN lines and that needs not too much fancy configurations unlike using with VOIP providers. We have a third line that I can attach to the gateway when the need arises. I have heard Patton and Audiocodes are better, can you give me your experience on these gateways? Configuration wise, how are these? Call stability, call clarity handling, echo cancelling and so on. Which is the easiest to configure and most stable. Thank you for reading. I hope we can switch soon, with your help of course.
