If i was to place a phone server in the DMZ, would i do it at the modem level or at the pfsense firewall level. We cant use PBX VPN because we use Grandstream phones. The Sangoma phones we have aren’t working with the VPN and EPM like described in documentation, and we don’t have 300 bucks for hours of looking by Sangoma. We need a solution for our remote phones that, now, haven’t worked in over a month. I can set up internal phone systems blind folded, but setting up a hosted phone solution, has eluded me.
HELP PLEASE.
If you have a pfsense in the remote sites, then you could:
- Create an openVPN client in the pfsense to connect to FreePBX VPN server, then
- Set the phones (IP address) to use the openVPN client as a gateway to connect to the FreePBX VPN server
Are you having trouble with registration or passing configs to the phones using EPM? Or Both?
Since you are using EPM, do you also have System Admin Pro?
I using both, but im not using redirect
They are trying now, but cant tell why the sangoma phone wont utilize the vpn to connect. sangoma sees no requests from phone to use vpn.
Thats the only thing we dont have. That makes great sense putting in a pfsense firewall with a vpn between theirs and ours. Not an option for us. One place has a company/building wide firewall, that messed with ours, and only one phone would connect at a time. The other we didnt think about doing because we had figured out the vpn puzzle with freepbx and grandstream phones.
If i changed that route to 10.6.0.0 will it matter?
Using the redirect server might be the missing piece of the puzzle. We have never used it with grandstream phones. We just configured them internally to the phone server. He is a very small company and his biggest is maybe 56 peers.
