Hi,<br>
<br>
Sounds like a flaky physical connection to me.<br>
Try new patch cables (DO NOT EVER use homemade patch cables, they cost
too much) and a different jack if in an office environment.<br>
<br>
If that doesn't fix it, try locking the switch port and/or the phone
port speed/duplex settings and turn off auto-negotiation. Try a
different make/model of switch (insert between phone and router).<br>
<br>
regards,<br>
<br>

Thanks for all the replies. I've updated client's router firmware,
which was very old. Now I've put MoH on for the whole day and see if it
happens again. MoH was doing the same thing, i.e. going down and coming
back up. When it went down, on the screen you could see message saying
'No IP', and when it came back up, same old IP was back.
<br>
<br>
Phone's firmware is the latest one, which is on their website, i.e. <a
href="http://1.1.1.14">1.1.1.14</a>. I know there exists some latest
but still beta version of a firmware, but I'll stick with this one.
<br>
<br>
There is no pattern when it goes down, it may does it twice an hour or
not do it for many hours. But I've noticed that Automatic Upgrade
Option was set to 60 min, I've now set it for 1440 minutes.<br>
<br>
Does automatic upgrade means only firmware upgrade or config upgrade as
well. Can I have config upgrade sooner than 1440 minutes on this phone?
