Hi

I found a lot of messages from AS5350 gateway.

Call awarded and being delivered in an established channel

The reason:
The user is assigned an incoming call that is being connected to an
already-established call channel.

Question:

1. Why the call being connected to an established channel ?
3. How to solve? is there any configuration on AS5350XM ?

Thanks any help.
