We have a Unity vm server at the data center. It is assign by PRI which has both 1800 number and a local number(416-123-4567). I have configured the SRST gateway and the call forwading for VM.
When users dial the 1800 number directly, it works fine. But when the call is forwarded to 1800 number, user hears 'The call cannot be routed'. But if I change the 1800 number to the 14161234567, both directly and forwarded call are working fine.
SO I just wondering what is the different from the Telco's perspective?
