Issues with Upgrade to R11.0.4
Issues with Upgrade to R11.0.4
Following the first upgrade to R10 I noticed the IP Office wasn't responding well. I started a continuous ping on the IP Office. I would get delayed responses of 20 ms to 5000 ms and 1/3 of the ping's would timeout.
This IP Office has approx 50 digital phones and another 50 IP phones at various locations. They would slowly come back on one after another. The PBX seemed stabilized after everyone has been connected (more or less 20 minutes).
Two days later we had to reboot the PBX to change a combo card that has been defect for the past 2 weeks. Following this reboot, the PBX would go through the same process I mentioned but would NEVER stabilize. We tried formatting and recreating the SD Card. We tried to power on the IP Office and plug in one card at a time. Once all cards and the DS expansion module all proved to be working fine, we tried plugging in one phone at a time. After all proved to be fine, we tried plugging in the PRI. Next we plugged in the WAN which contains only SIP lines. So far everything is up and running fine. We have a laptop in LAN 1 monitoring the system. We waited a bit with calls going in and out and everything is fine.
We plugged in LAN 1 to the local network, which also has the Voicemail Pro server, XIMA Chronicall + Multimedia server and +-50 IP Phones in various locations. All hell broke loose. At this point we do understand the IP Office is loaded with requests but nothing has been added recently and it never acted this way. The only new factor is the XIMA multimedia server but at this point I had all XIMA services turned off to limit the requests.
So we installed a new IP Office 500 V2 cabinet. Right away the IP Office responds with reasonable delays (1ms to 4 or 5ms) but the IP Phones took approximately 20 minutes to come back online one after another. At this point we're certain the IP Office network card was faulty and the issue is resolved.
Come in the next day and surprise we have some new issues. Voicemail isn't always answering, and if it does the sound cuts off halfway. No DTMF is supported once in the Voicemail. So we restarted the Voicemail Pro service. Issue resolved. A few hours later, the client mentions digital phones can no longer dial out. When they press on digits, nothing appears on the screen. If they press very slowly, the digits will go through.
So we now proceed to downgrade from R11.0.4 to 11.0.2. We read about different numerous issues online concerning 11.0.4. After this downgrade we come back to point A. The IP Office responds only 2/3 of the time with major delays. It takes approximately 30 minutes or so for everything to come back online. Yet after 30 minutes it all seems stable. For now...
The only errors we can see in the Sys monitor are the following :
ERR: Vil Cafeteria Terminal PGO Response !OK:(0x1)
TFTP Write:: Too many retries (from 0.0.0.0, 49597, to 4207) file=deltaconfig/svmail1/CHqoAZFPD9irGpRmDx8u6JbzCCinHJADCyeqGZK4020
Any ideas ?
