Hello, I've been having trouble trying to setup a direct remote extension for the past 2 days, and was hoping I could get some assistance on this. We have 2 sites, both with Static IPs Site A has a 3cx server Site B only has 3 users, and I'm trying to setup direct remote extensions to connect to Site A Both sites have Cisco ASA 5505 firewalls We are using Grandstream GXP-2100 phones I've configured port forwarding on both firewalls The Firewall checker verifies that the ports are forwarding correctly I've followed the instructions at the two links below, http://www.3cx.com/blog/voip-howto/remote-extensions/ http://www.3cx.com/blog/docs/provisioning-a-remote-extension/ The last step states to point the "Config Server Path" to "//PublicIPofPBX:5000/provisioning", and the phone will download the configuration, however nothing happens after this point. I created a test document at this location, //PublicIPofPBX:5000/provisioning, and I'm able to open it from the remote site, so I know that the port is open. Any suggestions? Another note, we have an IPSec VPN between the two sites. Is there any easier way to do this through the VPN? I know the other option was to setup a proxy server at the remote site, but management wanted this done sooner than later, so I figured I could get it configure remote extensions real quick, and have our phones up. I was obviously wrong.
