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
