I inherited a VOIP system at one of my clients. I have limited experience with VOIP and FreePBX. It had a failing Asterisk NOW PBX server. The SIP trunk comes in on a dedicated line from their ISP through an ESBC 9378-4b Session Border Controller. I have replaced the old PBX with a new Sangoma 40 PBX. I have setup the trunk and in/out routes, extensions, IVR… etc.
I have several issues:
The trunk says it’s online. However, when I dial the main DID it rings once then hangs up.
The original system had the phones on a VLAN 100. The old server had eth0 set to 192.168.1.7 and eth1 was set to 192.168.100.3. When I came on the scene eth1 was not plugged in. So I don’t know how the Digium D70 phones were getting their config. I tried adding a second interface on the Sangoma for the 192.168.100.x network and when I did I lost DNS resolution and internet access and I could not access the web GUI. Not sure where to go here. How do I get the phones to connect to the PBX if I can’t get a connection to the VLAN. Can I create a VLAN interface on the same port. of the Sangoma PBX.
The last thing I notice is that the Router onsite did not have a VLAN 100 setup on it so I suspect whoever set the old system up was just setting static IPs on everything.
