Using LittleSnitch I noticed that Messages (iChat) tries to connect to 17.154.239.222 over udp when I open the audio and video preferences for the application. Apple owns that IP address but does anybody know why it would need to call home?
IChat sends out connections to an IP address when configuring camera and mic settings

Go to settings on the iPhone. Go to the 'Messages' settings. And select Receive At.
See what it says there. It should be your phone number not Apple ID or email.
If you have a Apple email listed. You can remove it by.
Clicking the 'Apple ID youremail@me.com'
You will get a popup which lets sign out thus removing the mac email address.
I am running Messages via Mountain Lion, but I believe that the application is functionaly identical to the Beta for Lion.
I have the following regular issues with it in day to day usage:
- Badge counts are inconsistent, and it often says "1" regardless of reality
- Icon Bounce - it bounces in the dock a lot as if something has happened, when nothing (that I can see) has
- Slow syncing - when I have used iMessages on my phone, and then move to the desktop, it drip feeds the messages it needs to see to catch up really slowly, and you get a notification every 10 seconds or so for what can be a very long time if there is a lot to catch up on
Also, at least once (though this could have been a ML bug) it started using the wrong icon, showing a picture of a friend in place of my own avatar against my own messages. Investigation showed the "me" card had been ammended in Contacts...

The port is used to "set up Real-Time Transport Protocol (RTP), Real-Time Control Protocol (RTCP)" according to Apple.
According to wiki, "the Real-time Transport Protocol (RTP) defines a standardized packet format for delivering audio and video over IP networks. RTP is used extensively in communication and entertainment systems that involve streaming media, such as telephony, video teleconference applications, television services and web-based push-to-talk features."
Note: iChat became Messages.
