Hi. Ive just uncovered a possible bug. When a call is placed outbound from one ext. the Client (another ext. on different computer) will show that the ext is in use. (yellow button) After about 3-5 minutes this ext no longer shows as yellow in the client, but is back to green indicating its ready/idle even if its still in use. The line that the ext. is placed on is also indicated as green after same time period.
