TCP/UDP Port Usage

Can anyone help to explain exactly what/who the OBi is talking to?
QuoteHardwareVersion 2.8
SoftwareVersion 1.1.0 (Build: 1892)
There are several UDP sessions that come and go, connecting to ???  
I have SP1/2 each connected to Google Voice accts, OBiTalk is disabled, and Auto Provisioning/Update is disabled.  Most everything else is at the default settings.

UDP port 10140 at ec2-204-236-134-243.us-west-1.compute.amazonaws.com
UDP port 10400 at c-24-6-183-228.hsd1.ca.comcast.net
UDP port 10000 at DHCP-167-213-caltech.edu
and gotta love this one:
UDP port 123 at you.dontlike.us  (I thought NTP was from pool.ntp.org?)

I'm guessing the 2 long running TCP ports are the GVoice connections.

 :) Well it appears that I found a solution to the numerous UDP connections. 

Using the device config, I had to ENABLE OBiTALK Service, Reboot to ensure it stuck, then DISABLE OBiTALK Service and finally Reboot.

Now I only show 1 occasional UDP connection to DNS, and 2 TCP connections - to Google Voice I presume, since I have SP1 and SP2 setup that way.

Only an educated guess, but it looks like we need a better way to force a reload of the config settings after a firmware upgrade.
