Yeah, I actually am using PoE, but there's no wall jack used.. We have
our cables (cat 6) wired directly from the PoE adapter on the phone to
the PoE switch (Linksys SRW224P). We've only got 5 phones hooked up to
it at the moment, but it seems that all the phones are experiencing
this problem.  Looking back on my xferlog file, it shows the phones
downloading files from the FTP server randomly throughout the day,
which would indicate that they're being restarted at this time..  The
strange thing is, not all the phones are reset at the same time..  For
instance, I have in my log a phone being restarted at 2:58 AM last
night, another one at 2:47 AM, another at 1:38 AM and another at 11:30
PM..  I figured all of the phones would be restarting simultaneously,
but that's not the case..

I'm using FTP, and as stated above, I can see that the phones are
being restarted at random times, since the log shows the phones
downloading the ringtones and configuration files.  My SIP firmware is
1.6.5.0043 and my bootrom is 3.1.3.0131

You can take a look at my sip.cfg here:

although it's pretty standard, other than the 80's sitcom ringtones
that I've uploaded ;)

Could it be that my PoE switch is being overloaded?  Here are some
details about the switch and the power requirements of the phones that
I posted in a message earlier this year (the switch delivers 15 watts
per port, the phones only require 4 watts):

so as far as I can tell, we should be well within the power
requirements of the phones.

Thanks for the help guys,

Mike
