hoe to reset my phone i forget password

The IP 335 is an entry level phone so it is doubtful that there would be anything like a fuse in it. From what you've described here I would say the phone is fried. Moving forward I would recommend to always keep your important electronics on a good quality surge suppressor and/or a UPS. Good luck.

Are you using this as a stand alone unit or configured for an Asterisk server? You say you got a new modem, so are you using the same router? If not, you may need to open some ports using port forwarding rules. How that is done depends on the type of router.

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.

This sounds like an RTP stream issue. While SIP runs on port 5060 by default, the actual audio is run on much higher ports, 10000 and up. If your pbx system is not on a public address and you are forwarding traffic to your pbx via a router, check the RTP port range in your pbx and make sure you are forwarding those ports correctly. By putting the call on hold, you stop sending out audio traffic restart sending audio when you pick the call back up. By forwarding the entire RTP range to your pbx, this should fix your issue.

can you check either the display or the option itself if you have the Forward button? It might be there..

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.

You'll have to set up Port Forwarding on the router, to port forward a port from the 'local' zone to the 'internet' zone. And i do hope your not viewing the administration pannel on the thing in German. (polycom is german, as is their website)
