They're all Polycom phones. Mostly 450s, with a couple of 550s, a 670 and a 
SoundStation 6000 in the mix. Firmware 3.2.6 with bootrom 4.3.1.

Joegen, George, 

I noticed some messages in my sipXproxy log from a hang on a 
customer system just today, which may or may not be 
pertinent. Besides the parsing errors, I also see messages 
such as this immediately before the hang: 

"2012-08-21T15:40:56.031862Z" 
:269589:NAT:WARNING:pbx1.sipdomain.com:SipUserAgent-2:B5EBAB

90:SipXProxy: "'5FHSHt9cQ2XBS': Received unexpected event

FAB90:SipXProxy: "'5FHSHt9cQ2XBS': Received unexpected event 
SuccessfulResponse while in state 'WaitingForInvite'" 

Since this has been happening to some of our customers more 
than once within a 24 hour period, in order to keep them 
from cancelling with us we've had to resort to a watchdog 
script which sends OPTIONS messages to the servers 
periodically and restarts sipXproxy if it fails to respond. 
Obviously this is just a band-aid workaround until we can 
resolve this issue, since this means they incur 
approximately 3-4 minutes of service interruption every time 
this happens.
