How to fix Polycom soundpoint IP 335 with surge damage

"If you need to remove the resource files from a phone at some later date-for example, you are giving the phone to a new user-instructions on how to put the phone into the factory default state can be found in 'Quick Tip 18298: Resetting and Rebooting SoundPoint IP, SoundStation IP, and Polycom VVX 1500 Phones' at http://support.polycom.com/global/documents/support/technical/products/voice/SoundPointIP_Resetting_Log_Files_QT18298.pdf "

Makes sure your Firmware is all upto date. Had the same issue with the soundpoint ip 501.

You need to reinstall all the files back onto the phone. You can get the files from the Polycom Website. You can also follow the instruction from my Polycom 501 Fixya blog to see how its done.

It is not your T1. The T1 only controls the internet, not your local LAN. How old is the phone? It could be a bad phone....What system is it installed on?

Default Passwords:
To get into the web interface, the default username/password is "Polycom"/"456" (Note that this does not work with Safari 1.2.2.)
To get into the Admin interface on the hard phone, the password is "456". (Prior to v1.3.1, the web interfaces to the phone uses "Polycom"/"SpIp" as the username/password.)
The "user password" (not used much) defaults to "123".

To reset a lost admin password to default: at phone boot, during the 5 second countdown, push/hold 468* on the phone. Enter the phone's MAC address as the password. This will reset network info but keep peers loaded. Tested on Soundpoint IP 650.

Can you pls check the configuration file on the tftp server
some wrong information is there
pls compare with any other ip phone

I think you have to have the upgraded cable modem with the rj11 on the back in order to pull the voip dialtone. Hope this helps

As you have probably found, SIP phones are not supported until R5, which just came out.

This means the phone's SIP application has been erased. You will need to download the SIP app and BootROM from the Polycom support page, host the files on a boot server, and then point the phone to this server from the server menu so the phone will reboot and download the files.
