Can't add more user to the exist Enterprise on BW.

Can't add more user to the exist Enterprise on BW.

But I used to add users and deleted before. I don't know why I can't add more users.

Added user to the exist group is worked properly. I can't make a call and receive using added user number.

The following is the AS log.
