I've just interfaced an Avaya 4621 set to *@home. It's running the 2.2 SIP firmware released August 17th. I've run into some strange behavior with this phone. 1st, in order to get two way audio, I had to tell * that it was behind a NAT even though it is on the same subnet as the * server. Second, it doesn't seem to be able to dial any extensions or features that use the * digit in them. The phone remains off hook, and I get a fast busy after about thirty seconds. I also can't find any log entries that shoe the attempt was even seen by the server. I've completely disabled the internal dial plan inside the phone and the problem persists. Third, the mute button seems to disable audio in both directions, not simply the local microphone. Has anybody else interfaced one of these phones to *? If so, did you experience these same problems and did you find any solutions? I believe this is the first public release of SIP firmware for this phone and I know it hasn't been out that long. Thanks - Tom
