FIXED: AA sees TWO active calls when there's only just ONE active call.

Bug:
AA sees TWO active calls when there's only just ONE active call.

Example:
Say 17778889999 is my cellphone number, and I use it to call my obi.

When using {17778889999:aa($1)},{ph} at inbound route to invoke auto attendant, "Call Status" would show TWO active calls from 17778889999 to AA at the same time, when there is only one.
When I hangup to initiate callback feature, I get TWO simultaneous call backs from AA to 17778889999.

Older firmware like build 3647 do not have the same problem using the same settings.
Also "enable"/"disable" AA seems to have no effect.

Is this a bug or a setting issue?

OBI solved this for me. Turns out enabling secondary registration caused the problem.
