Our office has been running a trixbox appliance for the last few months with absolutely no problems. The trixbox appliance is connected to our network and is accessed by 10 PC's placing phone calls using soft phones through a SIP gateway. It's an extremely simple setup and functioned perfectly from implementation until yesterday, when it abruptly stopped working.
After a lot of experimentation, we have encountered some extremely strange behavior and seem to have narrowed down the problem:
- When the trixbox appliance is NOT connected to the network, the entire network functions 100% (all systems can resolve IP and find the default gateway, they can all access the internet and communicate with the server, etc).
- When the trixbox appliance is connected to the network with DHCP enabled, it fails to resolve an IP address and access the network. Approximately 50% of the time, it takes down the other systems with it immediately. The other 50% of the time, the rest of the systems continue to work for a little while, until eventually each PC receives a "limited connectivity" message indicating that while the systems acknowledge that the cable isn't unplugged, they are unable to access the network's resources. Further investigation reveals that at this point, the PC's all show an IP address completely out of the range of our network, with the default gateway empty.
- When the trixbox appliance is connected to the network with a STATIC IP and all network settings are entered manually (the way we've always had it), it's usually up and running for a little while (anywhere from 5-30 minutes) until it inevitably brings down the entire network in a manner similar to the one described immediately above.
We initially contacted our ISP (who remotely maintains our entire network) prior to discovering any of the results mentioned above. After several hours of testing, they concluded that every aspect of our network is fine, and that there must be some sort of internal problem, which turned out to be the trixbox appliance. What this all boils down to is that when the trixbox appliance is NOT connected to our network, the network functions perfectly and indefinitely as it always has. When the trixbox appliance is connected using either DHCP or a static IP, it always ceases to function and brings down the entire network with it one way or another.
We need immediate assistance, as our office is completely dependent on the trixbox appliance. Remote support is fine as we have technologically capable people in the office who can assist in the process. We can also grant you both remote desktop and VPN access to our network.
If you are qualified to assist with this problem or able to recommend someone who is, please contact me via PM or at (561)337-8908.
