Hoping maybe someone has some ideas about why I cannot get a Polycom 450 remote phone to register.
I have a test remote network setup, and have verified that if I send any traffic from it to my sipx proxy I can see the traffic at my local firewall. I am allowing all traffic from the remote network and can see UDP, TCP and ICMP traffic that I manually generate. If I take a working (locally connected) Polycom 450 and move it to the remote network, it will not register. If I check the firewall traffic, it appears the FTP traffic from the phone contacting the configuration server is all that gets generated. No other SIP, TCP, UDP, ICMP, etc, traffic is logged. If I manually clear the configuration server IP in the phone and reboot it, then no traffic is generated to my sipx proxy from the phone at all. This holds true no matter what settings I make to the phone, and I have tried all of the following settings manually at the phone which I understand overrides any config files applied. Setting the phones IP to a static and dynamic configurations. Setting the Outbound Proxy to static IP, Proxy name, static port, and tried all transport settings. Setting the Call server Settings to static IP, Proxy name, static port, and tried all transport settings. Setting line settings to static IP, Proxy name, static port, and tried all transport settings. Setting the local DNS name to the local and external domains. Wiping the configs and updating the firmware/software to 3.2.3, back reving to 3.1.3 Holding tongue to left and right side of mouth while making changes. It seems to me the phone is not functioning correctly, since it is not even attempting to contact my proxy, but if I set it to DHCP and boot it to the local net, it works fine. If I fire up a soft-phone on the remote net and point it to my proxy it registers and works fine too, so the routing and firewall settings are good. I am at a loss. Anyway, based on the last statement, my conclusion is regardless of what changes I manually make to the phone, that the configs must be taking precedence, and my changes are not having affect, but this is counter to my interpretation of the Polycom docs. Further proof to this is that this is only the case after the phone has been configured via sipxecs. I have tried making all the changes above thru the sipxecs web manager as well as local to the phone, with no success. However, if I wipe the phone and load vers 3.x.x and manually configure the phone, it registers. I have all my internal and external SRV records configured, and have followed every document I can find including DNS Concepts for sipXecs By: Michael W. Picher, and the Configuring remote workers cheat sheet. DNS aside, if manual phone configs take precedence I can't figure out why the 450 is not making any attempt to contact my sipx proxy when given the IP, Port, and Protocol. Any suggestions would be appreciated. Thanks.
