Hello, I'm testing 3cx right now, liking it so far. I have all ports forwarded correctly. I can make calls, including remote 3cx soft phone clients without issue using the sbc, windows environment. I'm attempting to remotely provision a polycom device for testing. I setup option 66 in my DHCP server and it correctly resolves my outside IP for my windows 3cx box. It doesn't appear that 3cx is provisioning the polycom phones correctly. I put the firmware files for the IP450 in programdata\3cx\instance1\data\http\inter\provisioning\<numbers>\<root with firmware> What I notice, is for the phone I'm testing, I only have a <mac of polycom-directory.cfg. There is not a <macaddr>.cfg file listed. I searched my PC for it, and I can't find it anywhere and that coincides with the error i'm getting on the phone : Unable to download <mac>.cfg, using existing config. I have a freepbx box with tons of extensions, so I'm fairly familiar with provisioning these types of phones.. I'm getting a access denied 403 error on HTTP when attempting to browse to it, but again, the config file for the phone doesn't seem to exist. I've tried recreating the extension and it's still not generating any kind of config that I can see..but I'm new to the system What am I missing or what should I try? I'm pretty sure I'm going to have this same issue locally when I try it tonight. Thanks.
