You can use the hardware restore button on the Polycom HDX system to reset
the system in one of these ways:
• Restoring configuration-Restores the configuration, which resets most
system settings to default values.

• Factory restore-Completely erases the system and restores it to the
software version and default configuration stored in its factory partition.
If you follow this procedure while a USB storage device is connected, the
system restores from the USB device instead of the system's factory
partition.
The restore button is on the front of the Polycom HDX 9000 series system, as
shown in the following figure.





The restore button is on the front of the Polycom HDX 8000 series, Polycom
HDX 7000 series, and Polycom HDX 4000 systems, as shown in the following
figure.




The restore button is on the left side of the Polycom HDX 4500 system, behind
a wire mesh screen, as shown in the following figure.





Use a paperclip to press the restore button through the wire mesh covering
that side of the system. to reset the HDX Series system we can press the restore button over 15 second.

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.

A Google search netted this helpful article. I appears you'll need to contact the service provider.

Due to the age of the SoundPoint Pro, it some of its features are not compatible with newer phonesystems, such as CableVision. There are no software updates for the SoundPoint Pro, and as long as the Caller ID is enabled there are no other settings or adjustments that can be made to workaround these kind of problems unfortunately. I recommend contacting your service provider to see what kind of caller ID signaling they are using; most likely they will be using a newer digital system, or MDMF which is not backwards compatible with SDMF or earlier CID receivers.

Check on the router if you are distributing enough IP addresses.

Web into the unit by it's IP address and go to "Home Screen Settings" and check "system".

The issue isn't exactly resolved. This appears to be due to an incompatibility of the Polycom Se-225 on our Meridian 1 phone system. But Converse handsets with MWI work fine. I have a partial solution by disabling the lamp (LPD on class-of-service), while leaving MWA setting. This allows the interrupted dial-tone when the user lifts the handset.

Make sure you have the latest BootROM and SIP config files for this polycom(sip.ld, sip.cfg, etc...) on your TFTP server. If you do not have this - download from here - http://www.polycom.com/support/voice/soundpoint_ip/soundpoint_ip501.html

If you do not have a TFTP server, you can download one for free.

Best to contact your phone system provider, to determine if it is or if it still under warranty.These types of items are generally not user serviceable.

Please check with your Internet Service provider. They might have a firewall which blocks the ports used for video conferencing
