I just purchased a Polycom Soundpoint 400 off of ebay to test with asterisk and Im having alot of problems configuring the phone initially. Can someone tell me how to do this? I have successfully setup a Polycom Soundpoint 300 with asterisk, but the 400 seems to be a bit different. It grabs an IP address but constantly tries to retrieve a config file from a tftp server (which I dont have). Can someone tell me how to set this phone up to work?
