I have a Uniden wireless phone system (one of those Costco packs) hooked up to the Obi202. Has anyone noticed that when you push the end button to hang up, it takes a long time for the phone to register that it's back on hook? I tested by hooking up the phone to an Obi100 and the hangup was pretty much instantaneous. I can hit end, and then proceed to dial or redial a number right away. Not so with the Obi202. I have to wait for about 5 seconds after I hit the end button before I can redial.
