I will have to assume I have an issue with the port forwarding on their Cisco E1000 routers then. I have the DB programming setup, and the listed ports forwarded to the HX. The only thing I was missing was the TFTP server port in the phone. Same problem. More than anything I wanted to verify that it will work as a remote user (not using teleworker), just a matter of playing with the ports/firewall to get it to work..
Thanks for the suggestions!!
Generally, no port forwarding needs to be done at the remote site at all... If there is an issue it is with the firewall/router at the host site, we use the Cisco/Linksys E series all the time at remote offices and they work brilliantly. Actually, the best router we have used for smaller, remote sites for the money is the Cisco/Linksys WRT54GL (must be the GL model, Newegg has them for $49), then replace the stock firmware with Tomato firmware by Polarcloud available here (
http://www.polarcloud.com/tomato), and it is free. Rock solid, run them for literally years without a single reboot.
On the local (5000) end, make sure all these ports are port forwarded to the 5000's internal IP:
- Voice Traffic (52xx/53xx): 69, 20001/UDP; 6800-6802/TCP; 3998 and 3999/TCP, 50098-50508/UDP; 6004-6261/UDP
- Maintenance/Remote Web Portal Users: 44000/TCP; 443/TCP; 22/TCP
