Different versions of firmware may have different features enabled
requiring a different amount of power. It is quite possible that
changing to a different version of firmware may cause these POE problems
to surface. As you are running on POE, you should do as Jim suggested
and change to external DC power to see if that fixes the problem. If it
doesn't, then at least you've eliminated that possibility. If it does,
then you can either run on external DC power permanently, or try a Class
3 POE device to see what result that gives.

Hi again Huijun,
Thank you for the reply. I understand where you are coming from.
They are PoE powered. I didnt suspect about power issue as the previous
ROM 4.0 and SIP2.2.2 worked almost with no freeze for almost a year.
When i update the SipX from 3.10.2 to 4.x stable and upload the latest
ROM and SIP firmwares to device files-> followed by send phone profiles,
this intermittent freezing arise.
I didn't play with the Polycom phone settings. As all phones are 330s, I
had one phone group that contains all Polycom 330s, where i can make
sure all of them share the same config. The config is using the defaults
that comes with sipx except the volume persistence and 24-hour clock
adjustments.
As i moved from one ROM+SIP version to another to see if i can get rid
of the freezing/hanging, i start suspecting that the XML config files of
polycoms might be corrupted.
But I am not clear on where to look and how to diagnose it. If You can
share few pointers on how to locate and check for validity i would very
much appreciate.
Do You use Polycoms? If You do which ROM and SIP version proved to be
rock-solid with latest stable Sipx 4.x ?
all the best!

Perhaps it's not firmware. Power has been a big issue for Polycom in
certain situations. How are these phones being powered? POE
switches, especially the cheap ones, tend to be problematic. The
phones are supposed to be class 2 devices, however, class 2 power/port
settings seldom work and result in frequent reboots and freezes. I
would make sure they have full class 3 power or use the external power
supply for testing and see how it goes.

Hi Huijun,
I have tried SIP 3.1.3 revision C (tried bot split and combined separately)
with ROM 4.1.3 and noticed few issues and intermittent freezing.
Then I've lowered the firmware 3.1.1(base version) and rom to 4.1.1(base
version), which solved the hanging on transfer issues but the intermittent
freezing is still present.
The last known-to-be-working (before i update sipx from 3.10.2 to 4.0.1)
rom+sip were rom4.0 with sip2.2.2
Didnt have any issues with transfer nor intermittent freezing with that
version.
As i've came across in list that users higlight the support for latest
polycom firmware, i've tried the latest and slowly downgraded the versions
of rom+sip and tested again. After uploading the files and activate i've
"send all profiles".
I also noticed 90 to 95% of the phones would freeze when they receive the
remote-restart and had to be manually booted.
Since I'm using the latest sipx stable, i don't wanna go back to old rom and
sip and find the most stable version for ROM and SIP (sipx 4.x)
I would also love to understand where i can look for troubleshooting or
validate XML files generated?
Under Device Files, there is a button "Install default firmware" but i dont
know what it does as couldnt any documentation.
Clearly need some guidance from experience Polycom users running the latest
sipx.
all the best!

Subject: [sipx-users] How to diagnose Polycom Phone Freezing
Following the update to sipx 4.0.1 and SIP 3.1.1 with ROM 4.1.1 (base
versions, not revisions) device files for Polycom 330 phones, users are
reporting very frequent freeze - which occurs either during
conversation or simply when they come back to office.
1) which SIP & ROM would be more stable for Polycom 330s for sipx
4.01.
Your firmware appears to be too old. You need to upgrade to 3.1.2 or
later.
As Paul pointed out, Polycom SIP Application 3.1.3 has been released.
You can get it from:
http://polycom.com/support/voice/soundpoint_ip/soundpoint_ip670.html
Please let us know if the problem goes away with the newer firmware.
Thanks
Huijun
