[asterisk-users] Trouble with Polycom phones

[Kevin Smith]

Hi everyone,

I have been running into a few issues with Asterisk/polycom and I am 
running out of ideas. This problem has been ongoing for the last couple 
of weeks. I will try to be as detailed as I can, but I might leave out a 
few details. Any suggestions would be greatly appreciated.

Our setup: Asterisk 1.2.22, Fedora 4. Co-located to our PRI providers 
facility. Comes to us via a DS3 to our other co-lo, then is sent via 
wireless to our office. We also have another office in another state but 
the connection is pretty much identical (they may have different 
wireless equipment) except the path it takes.

About 3 weeks ago, our phones started to reboot randomly. Sometimes 
within 5 minutes, and sometimes up to an hour, but they were pretty 
consistent, and it didn't matter if the agent was on the phone or not. 
Asterisk would only tell me that the phones were not reachable, which 
clearly was the case since it was rebooting. At the time, they were 
running I think SIP version 1.6.6. However, the odd factor to that, was 
the office in the other state was not having this problem (running 
1.6.6) and my phone and my supervisors (which we were testing SIP 2.2.2).

After having our phone company test the DS3, there were some errors 
found, and correct and that solved the problem for a few days. Which of 
course, it started to happen again. However, this time there were no 
errors on the DS3, and again the same problems were occurring, but my 
phone, my supervisors, and the other states were fine. So I decided to 
upgrade all of the phones to version 2.2.2. So that at least solved the 
reboot problem, but I ran into another problem.

Now, the phones lose their registration with Asterisk. My bosses phone 
does it every time he receives a voicemail. Most people can go a few 
hours without having to restart, but then sooner or later, it loses its 
registration. From what I can tell, there are no errors in Asterisk, no 
errors in the logs from the phones booting. I can even ping the phones 
from the asterisk box when this happens, but they just won't re-reg with 
the system. Now my phone has been up almost 3 days now, but other phones 
are still having this problem. Also the phones in the other state are 
not having this problem AND are still on 1.6.6.

Anyone have any suggestions on something to look at, test, try, etc? I'm 
completely stumped.

Thanks,
Kevin
