We are testing remote IP extensions. Our vendor tech had me set up the IP extensions (2 of them)on our 412 controller, then connect the IP phones in the office and program the settings for internal connection and it connected correctly and recognized the extension. We left the port at the default, and edited the rest of the settings to match the IP addresses for the controller, the phone itself and the file server, and put in the correct VLAN.
Then I took the phone home. I have a Linksys BESFX41 router. IPSec is enabled. I can connect to the VPN at work through that router from a company laptop with no issues.
I plugged the IP phone into the router at home, and it went through the connection routine. When it asked me to press * to program, I did so. Per the tech’s directions, the only setting I changed was the router IP – I put in the Public IP for the firewall our VPN routes through, which is what the tech said to do. That didn't work, so I tried the Public IP for the router in that location. that didn't work either. The tech also admitted he hasn’t really done this particular setup before. The firewall and router for VPN access are not in the same office as the controller the extension is set up on. The controller, file server and phone ip are on a different subnet than the data center. We have an MPLS WAN that connects all of our sites.
What am I missing here? Will this even work? Our vendor does not have a lot of experience in this, so we are trying to sort it out for ourselves. From the other postings I’ve seen, it doesn’t sound like it will work without going through some serious hoops.
Any assistance would be really appreciated
