Calling via specific routes
In the OpenCom 1000 the connection to a particular subscriber is set up either automatically or via
specific routes. Your system administrator sets up these routes in the OpenCom 1000 and specifies
for each route how it is to be seized. By predialling the route code before the (internal or external)
call number you can select a specific route manually for the connection you want. Selecting specific
routes for your calls allows you for example to quickly reach the subscribers you want at the branch
offices of a large corporate network. Likewise, by entering a route code manually, you can log the
call charge data separately for your private and business external calls.
Always enter the route code before the call number you want to dial.
Your system administrator will provide you with the relevant information about the current routes
and their codes.
