Hi All,
I'm running into a similar issue while attempting to configure an x-lite client on Windows 7. For the time being, I'm on the same network as all the 5330e's, so there shouldn't be any network issues.
I created a generic SIP extension 202. X-Lite appears to be connected, and can make outbound calls to extensions as well as to outside lines. The issue I have is that when 202 is called from an extension, nothing happens for a while - doesn't show the called party's name, nor does it ring - and after about 30 seconds, the display shows 'busy' and I get a busy signal. Curiously, If I quit X-Lite, then call 202, the display shows 202's defined name and just has a busy signal.
My STATE shows similar to the above.
Hot Desk : 202 Login active at SIP                                              
  Location    | Device               | State         |  Owner  | ID   |Status

 1 3  1 107  2| Alternate Codec      |Out of Service |         |      |

Any ideas?
TIA,
