NEC UM8000 Help -No Internet

Jump to solution

I have an SV8100 IP PBX with a VM blade in it. It's the Univerge UM8000. I also have a NETVANTA 1500 and have seperated the VOIP and DATA traffic on my network into 2 VLANS. Everything is working great with 1 exception.  The voicemail blade cannot reach the internet because I presume when I changed the network settings it no longer as a default gateway? 

We need it to contact an SMTP server so we get voicemails to our email.  When I try to check for system updates it says it can't connect to the internet.  I've tried SSHing but I don't know what the SSH login is.  I've tried everything.  Does anyone know these systems and can offer assistance?? Thanks in advanced!

I've fixed this.

For anyone else with this system, I'll run down the process.


I SSH'd into the VM blade using Putty. Once in you can check network settings under Configuration>Network.  Mine were correct so I ruled out the wrong gateway address.  I then went back to a previous menu and there was a command prompt.  I tested pinging locally and wasn't getting replies from the Default Gateway.  So, I knew my issue was probably route related.  Sure enough I checked, and my route on the DG was incorrect.  I fixed this and was pinging Google right away. Basically, for return traffic to hit your VLAN2 (voice vlan) you need a route on your DG pointing to that network with a gateway address of your DATA VLAN.
