IPO500v2 r11.1.2.3 - system reboots - probably caused by 3rd pty endpoints?

Hi all. For your information, if you would encounter the same situation.

I have had a service request at Avaya Support for a few weeks now after upgrading a 500v2 from 9.1.6 to

This customer with 35 cordless SIP phones (Ascom i63) been running for 7 years with r9.1.6.
After upgrade to the IPO500v2 rebooted constantly!
Tried 4(!) other IP500v2 with different releases between to 11.1.1+ and configs created from scratch.
All started rebooting when connected to customer LAN. That was some pretty nervous 42 hours work in 3 days!

After tests with shutting down WLAN (IPO did not reboot) and shutting down all 3rd party phones, upgrading all phones,
I managed to get the system "stable" with phones on WLAN (with only 10 reboots in 6 days)
The customers original finally bricked totally on a friday morning, so I set up a brand new installation of an IP500v2 r11.1.2.3, meticulously created config from scratch. The IPO rebooted "only" 2 times a day and I set up a PC for monitoring and collecting SSA snapshots to send to Avaya.

Today they provided a Critical Patch for
Will try patching as soon as possible and cross my fingers, hoping to avoid a hart attack..
I'll keep you updated.

FYI, the critical patch has been working for a week without IPO500v2 resetting once.
Avaya has confirmed to me that this fix will be a part of 11.1.2 SP4!

The root cause was that ti IPO could not handle the way these 3rd part SIP phones sent registration messages (contencts and timing)
