How many lines (circuits) do you have going to your system? Is it possible they are out of order? Give me your ISDN numbers and I'll try to connect to you. Where are you located? My e-mail address is [email protected]

I have looked all over trying to find this for you and you are correct, it is no longer listed anywhere, but Polycom definitely has it in their archives on a server somewhere.

Contact them at 1 925 9246000 and request the software, they should be able to email you a link to it.

All old links are dead / gone but it must still exist, they wouldn't just leave their customers hanging like that.

On the Polycom support website the manuals are available.

On the Polycom support website download the documentation for the Viewstation SP. It is very similar.

First you should check if the power supply is working. You can buy a different one on ebay or if you have a second one you can see if that is the cause. If your power supply says "Spectre" instead of Polycom then it is a good chance that the power supply is at fault. Those weren't so reliable.

If you connect other video sources to the back can you see those? If yes, then good chance that you have to replace the camera. You could also check if the camera cables are still all well connected by taking it apart.

You cannot go straight from 7.2 to 7.5.4 you must at least do one in the "Middle" first, you can go to 7.4.0 ? and then to 7.5.*, as there was an update later on that depended on another update prior, I think that those upgrade paths should straddle the upgrade paths.
Also remember to install as administrator too.
Usually when they wouldn't connect it was because they, it, were faulty, or the driver was.

I just called Polycom and the guy said it starts with 0003 or 0004. Sure enough I had one of those numbers, it was the same as the serial number on the box the phone came in. This number is found on a sticker on the back side of the phone. Easy to find, but not labeled as a "mac address"

The microphone is called an "Electret Mic", this has a capacitance microphone, and an internal amplifier all in one package, These require a 5 - 12 Volts DC working voltage, and indeed go faulty, very easy, as you related. You can get these Microphones from Radio Shack or similar, they are very common. They have a positive and a negative, the case is always negative, the center cable is usually Positive, with the outside or Shield, and easy to re-solder. Check, the circuit, and make sure polarity is correct, and/or the cable isn't broken, or otherwise wrong. There are usually only two connections, so you shouldn't have too many problems troubleshooting, You should have 5 VDC on the lead that goes to the Mic, and the Mic, should have a resistance of about 1 - 2 K Ohms.

Which exact unit ? This is a known problem with orignal 'Spider' PSUs for the Viewtation range (reboot issue).
