We're using a couple of h323 IP Phones (innovaphone ip200) w/ asterisk. Basic call setup works, but we can't get call transfers to work: On pressing the "transfer" button on the phone (getting a new dialtone) the 2nd endpoint is disconnected. Any idea if we can get this to work? Same reaction using the innovaphone ip400 gatekeeper and using gnugk. Asterisk version is 0.7.2 release. Thanks, Martin
