I've taken a quick look at the NAT traversal plugin and it seems to be
not accounting PUBLISH as a potential stream modifier. But it is not
clear to me how it would cause a hang. Can you disable session-timers
in the phones and see if that somehow lessens the occurence of this
incident?

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"

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.
