I have been running through hoops, to figure out this problem : For remote Extensions, you can hear voice in from the other end, but you cannot send your voice out!!! So today came the SP1 for the console, and the update for the 3CXPhone,I have updated to SP-1 and the 3cxphone and what do you know, it is finally working ......about time.... Good job on SP1 and 3CXPHONE updates Now, I have to figure out the Echo thing for remote ext, really too bad, I guess this has to do with SPA-3102 settings. I really think many of the problems I find people asking about here are due to Gateway setting (and firewall issues) than anything else. Anyone with an updated and proper setting for SPA3102 @ 5.2.13(GW002)? If I was a tech savy person, I would totally put up a page for the proper settings, but I'm a novice and I don't want to confuse others, and post half cooked settings This one is outdated and not comprehensive, http:/ /www.3cx.com/voip-gateways/linksys-3102/ - NO LONGER AVAILABLE and have some serious baffling things, like the outbound proxy is left emtpy!!
