Thanks for responding, Brian, Chris, and Ghulam. To answer your questions, I am using bootrom 4.2.1 or 4.1.4 (depending on the phone model because some don't support the later bootrom) and also SIP 3.2.2 or 3.1.4, again depending on the phone model because of lack of support for 3.2.2 for some of the older Polycom models. I'm using the split SIP image. With regards to Chris's suggestion about switches, we have the Polycom phones hooked up to Linksys managed switches and Dell managed switches, and the Polycom phones spontaneously reboot on both switches. I'm pretty sure the Dell managed switches are not dropping link. I don't think the Linksys managed switches are either, but I'm less sure there because we've had some problems with the web management interface being a piece of crap in the past. With regards to Ghulam's observation about speakerphone use, our Polycom phones reboot even when not on speakerphone, so that's not it. I've uploaded some of my config files here: http://209.190.22.48/fs/polycom/ They are the same as my real config files, except username, password, and hostnames. For the most part, they are the factory default settings. I would love to see any config files you might be willing to share, to compare your config settings to mine. Also, one thing that came to mind: how are you specifying the server and proxy addresses? I am just using a hard-coded IP address with no DNS magic. Do you think that would make a difference?

Now you failed to tell us what Firmware Rev you're running and what options you have turned on? /b On Mar 24, 2010, at 8:35 PM, Wellie Chao wrote:
I am using Freeswitch and I have some phones that spontaneously reboot (often in the middle of a call).
I did some searching around on the web, but didn't find any information that really applied to the problem I'm experiencing. I have a few dozen Polycom phones and a handful of Linksys phones of various models: Polycom IP301, IP320, IP331, IP430, IP501, IP601; also Linksys SPA901, SPA921, SPA941.
I also have snom phones, but they don't reboot spontaneously. It's only the Polycom and Linksys phones that reboot spontaneously, and it seems to be correlated to call volume. Heavy usage of the Polycom and Linksys phones causes them to reboot more frequently (i.e. shorter duration between the reboots). For people making 50 calls a day, the Polycom phones spontaneously reboot every three days or so (and always on a call, it seems). For people making one or two calls a day, the Polycom will go months without a spontaneous reboot. This correlation between call volume and reboot frequency leads me to believe that there is some bug in the Polycom firmware, perhaps some of overflow condition that accumulates over time and eventually causes a crash (and subsequent reboot).
I was wondering if anybody else experienced something similar, and whether anyone had developed a solution. One thing I am considering is to set up a script to reboot the Polycom phones in the middle of the night every day, which would hopefully prevent them from spontaneously rebooting during the day by preventing the phones from ever reaching the overflow condition (if that is indeed what causes the reboots). A nightly reboot would be a hackish way of fixing the problem, so I'd also love to hear if anybody has any other speculations on what might be causing the spontaneous reboots. We have phones in multiple buildings, and we've discovered that the spontaneous reboots happen on phones on different networks, so it's not specific to a particular LAN segment. For the most part, we are using the standard config files for the Polycom phones and for the Linksys phones.
