I've have had problems with calls getting cut off prematurely using Gateway (GXW-4104/recent firmware udpate) and SPA-921 phones with most recent firmware update as well. It doesn't happen all the time but we had to hard reboot the gateway to make the problem be temporarily fixed, at least twice a day. Anyone else having issues with this kind of Gateway? There are only two PSTN lines attached to it. No other problems are experienced but clients are getting annoyed with this instance of getting cut off in the middle of the call. Can someone tell me what work around they had to do with this kind of setup? Thanks.
