Hello - after upgrading last night from MT 18.104.22.168 to MT 9.1.3-6.cl6 all inbound calls fail to busy signal. I was unable to restore the inbound calling to a working state so I reverted to a backup of the previous version (works just fine.)
Attached are 2 files detailing test calls to the same number: one is after the upgrade (IB call fails to busy) and the other is after the restore (IB call successful.)
Any thoughts how to sort this out?
Thanks in advance.
