Hi All, It's me again! Lately i have been checking the logs and found the following entrance: Call or Registration to 0115515997651202@(Ln.10000@BROADVOICE) has failed. XXX.15.XXX.6 replied: 486 Busy Here; from IP:xxx.xxx.xxx.xxx:5060 What does it exactly means, any clues? This means the trunk cannot process the call or that the phone is busy? Thanks!
