Can't register remote extensions

[mbagshaw]

I have never had much luck getting remote extensions to work with my Quadro 2X - sometimes I have been able to register a remote soft phone (on a PC I use when I travel) normally, but I nearly always have problems - sometimes they can make calls but not answer them, I can make and receive calls but not hear anything. In desperation I used a VPN connection to my router and connected to the Quadro (which itself is connected on its WAN side to my local network) and connected the remote soft phone and two other soft phones on computers on my local network to the Quadro on its WAN side as local extensions. This was working fine until the other day when my system was hacked into, so I shut down the ability to connect a local extension on the WAN side.while that now seems to have protected my system, I can't use the soft phones on my local computers as phones (using the Bria 3soft phone which is brilliant because I can call directly from my Outlook address book or by clicking on the phone numbers in webpages), nor can I use my remote soft phone through a VPN connection.

My setup is fairly straightforward - a Draytek 2820 VPN router with dozens of devices on my local network, including the Quadro. The Quadro is running firmware version 5.2.48 and various Cisco, Snom and Siemens IP phones are (successfully) attached on its LAN side.

I have enabled three of my extensions as remote extensions and have put the appropriate remote user ID and password settings into the soft phone (Bria has fields in its Account Settings for both Username and Authorisation Name - I have tried it with just the Username filled in, and with both filled in). I have "Fallback to local extension when not registered" and "Symmetric RTP" both checked on these extensions.

I have tried every combination of firewall settings I can think of on the router including "Open Ports" 5060 and 6000-6099 to the Quadro (it has a fixed IP address on its WAN side on my local network), "Port Forwarding" of the same ports in the router (I'm not sure what the difference is between "open ports" and "port forwarding" is on the Draytek router, but neither seems to work anyway), and I have also tried to DMZ to the Quadro.

The end result of all of this is that the soft phone simply won't register (Bria gives me a message "Problem at the server - SIP error 408"). Is there anything obvious I am not doing?

Make sure you are not using port 5060 for any other devices on a different IP on your LAN. If you are slo portforwarding 5060 to another IP device then use another port for SIP register. If you have wire shark, it may be worth investigsating the packet data to see whats going on.
