<div>Dear All,</div>
<div> </div>
<div>I have 2 CallManagers (4.01) in different cluster, connecting via intercluster trunk. Both of them are using software conference bridge. When I tried to make conference call with IP Phone which registered in 2 CCM, it always failed. For example, phoneA & phoneB are registered in CCM1, phoneC registered in CCM2. phoneA call phoneB and then conference phoneC, after dialing the phoneC DN, it just got disconnected. Please kindly advise if you have any suggestion or comment. Thanks a lot in advance~</div>

<div>Regards,</div>
<div>Alan</div>
