Seting Up Remote Extensions
Five5
Based on various posts in this forum I have tried to work out how to set up a remote extension. But I have failed to get it to work based on this ad-hoc information. I am sure I am missing something fundamental.Would anyone who knows care to write it down for us including all the necessary steps at both the GXE and GXP ends, and any necessary firewall or network changes. It would be greatly appreciated.
Good point. Here are some details. Office network details:ADSL Modem > VPN Router/Firewall > Switch > GXE5028The GXE has the LAN port connected to the switch, and the WAN port connected directly to the router/firewall.The GXE has DHCP switched off, the Router/Firewall is performing DHCP.Connected to the GXE are GXP2020 VOIP extension. Remote location 1:ADSL Modem/Router > Switch > GXP2020 VOIP extension. Remote location 2:ADSL Modem > VPN Router/Firewall > GXP2020 VOIP extension.This extension works just fine as it is going through the VPN and is not a remote extension. But I would like to make it a remote extension as we loose the VPN connection every now and again even though the ADSL service seems fine at both ends. So to avoid the dropped calls as the VPN fails, I would like to make this one a remote extension as well. Remote Extension 1 is the priority, Remote Extension 2 is a nice to have if I can have it. Thanks.
AnthonyThis is how I have set it up:
- At the GXE end on the router/firewall
- Open up ports UDP 5060 to 5061 and forward to IP of GXE
- Open up ports UDP 6000 to 7099 and forward to IP of GXE (for RTP)
- Specify IP of GXE as DMZ host
- AT the remote end
- No need to open any ports on router
- On the GXP
- Enter the Public IP address of your router in the SIp server field
- Enter the Sip User ID and Password as set on the GXE for the remote extention for account 1
- Enter a stun server (i use stun.fwdnet.net:3478)
- Repeat for any oher account
- In basic settings tab either assign IP address by DHCP or
- Assign a fixed address and enter the gateway address etc
- Reboot the GXP and you should be on your way.

Thanks Vince.There are a few steps in your instructions I did not complete so the list was a great help. I am not working as yet so can I throw a few more quesitons at you.Presently I have the GXE WAN port connected to the Router/Firewall and GXE LAN port connected to the switch. I tried removing the LAN to switch patch and the PBX begun to stop working with the phones.Can you direct me to the best config of the patch cables to network gear. Use both GXE WAN and LAN ports or should I be working with just one or the other working?Five5

The system can be arranged both ways. You can connect the WAN port to the router and the Lan port to a switch as long as the WAN port and the LAN ports are on different subnets. That is, if your WAN port has an IP address of 192.168.X.Y your LAN port should be 192.168.A.B where A,B,X and Y can be 1-255 as long as A and X are not the same.
This means that your IP phones will need to have IPs in the same subnet as your LAN port. To get to the WEB UI of the phones and the GXE you need to have a PC with an IP address in the same subnet as your LAN port.
Alternatively you don't need to use the LAN port at all and connect everything on the WAN side. This way everything will be on the same subnet as the WAN port of the GXE and avoid all the confusion. This is how I have set it up and everything works.
If you were using the router feature of the GXE then you would need to use both WAN and LAN ports.
Hope I didn't confuse the issue.
