I noticed that on earlier versions of the firmware I was able to crash these phones with a flood ping (ping -f <phone-ip>). I send this notice to Cisco but never followed up on it. How are you powering this phone, POE or wall cube?

Hello John, I have a similar story with one of mine.. If i use a cell phone near it, it reboots :) The other ones are fine.. I think it's a hardware problem, but it only reveals itself with the cell phone radiation :> Sunday, December 14, 2003, 10:59:14 PM, you wrote: JT> This is almost certainly not an Asterisk-specific posting, but due JT> to my inability to find a VoIP-focused Cisco list, I'll post here in JT> the hopes of finding a more diverse user community.
