| [Other] trying to config a Polycom IP 500 for Quantumvoice
I'm tearing my hair out at this point. I've already spoken with someone at QV, and - even after connecting to my PC and accessing the phone's built-in Web site - he didn't see anything obviously wrong. I've also turned off my router's firewall, and I've even put the phone in DMZ. No matter what, though, it simply won't register with QV at all. I'm welcome to ideas. |

Castle Rock, CO | was this phone set purchased new in a box, or second hand? |

Castle Rock, CO | when the phone boots up, does QV attempt to over-write the previous carrier's configuration files? |

Do other line appearances (with other providers) work ok?
Is your phone set up to fetch a provisioning file from QV? From your own server? Is it actually fetching the file, e.g. does the line button show a plausible label?
Do you know if register requests are going out? Responses coming in? If so, what error code? Before or after authentication? |

I don't have another provider. quote:

The previous owner used central provisioning of some kind, but I intend this phone to be completely standalone. It's unable to contact a boot server, if that's what you're looking for. quote:

I have no good way to tell.  |

I just tried to change the line label. It still shows "SoundPoint IP" instead. |

I rep Nuvio, and the Polycom 500 is one of the workhorses, so I have a little familiarity with it. Out of the box, the Polycom assumes that it will be on an internal network, like connected to an Asterisk or other IP-PBX. To use an outside service provider, the phone needs instructions to get onto the internet and search for the selected provider. Did QV guide you to change the server address so that it would communicate with their network? |

Yes. As I mentioned, the QV tech support person said that he didn't see any problems with the config as shown in the phone's Web pages. However, he wasn't terribly familiar with Polycom phones. |

Yes. The previous owner's settings were still in there, so I had to clear them out and put in the QV ones. Oh, and I've also reset the phone to factory defaults - although, to my surprise, it didn't clear out very much in the way of config. |

| I would try to isolate any potential firewall and port issue, by plugging the phone into the broadband as close to the wall as possible ... disconnect everything you can on your side of the broadband modem (or T1 router) just to see if the phone can register. Or take it home and plug it directly into your DSL or cable modem. If the phone registers without all the work stuff in the way, then your network guy will have to help you troubleshoot. If the phone won't register with a clean IP connection, then QV will have to continue to help you. |

IMO, don't work in the dark. Find a way to see the Polycom's traffic, e.g. with Wireshark, so you will know what's wrong. One way is with a old dumb (10 Mbps) hub. Another is with a managed switch. A PC with two NICs will also work -- you might have one with wired and wireless, or you may have a USB or Cardbus NIC that you can plug into a PC that has a built-in NIC. |

Yeah, I've tried several different things. We have DSL with PPPoE here, and the modem doesn't do PPPoE auth, so I can't just jack the phone straight into the DSL modem. It's as close as can be at this point. |

Good idea, I'll try that and report back. |

| I tried to find an unmanaged hub - no dice. I did manage to setup a connection bridge on a WinXP laptop (phone plugged into laptop Ethernet jack, laptop wireless connected to router). However, if I'm reading Wireshark correctly, the only thing that the phone is doing is getting an IP from my router - nothing about even trying to setup a SIP connection. Dammit. All firewalls are turned off. Ideas? |

| You may want to try Internet Connection Sharing instead of Bridging. That's because most recent wireless NICs don't support promiscuous mode, so unicast packets addressed to the Polycom's MAC address won't be received. If you have a USB or Cardbus Ethernet that you can plug into the laptop, that is another way to avoid the problem. For a sanity check, plug another PC or known working device into the laptop and verify that it can access the Internet and have its traffic logged as expected. (You will need a crossover cable unless at least one end is auto MDI/MDX; gigabit NICs usually are.)
If the above is not your situation:
Is the Address under Line 1, Server 1 a name or a numeric IP address. If the former, DNS is needed. Do you see any DNS requests? Is Register set to 1? |
