For each collaboration you wish to configure for a call-triggered flow, you must perform the port configuration on the collaboration object.
To configure a collaboration port for a call-triggered flow:
If this window is not currently displaying, navigate to the Collaboration Objects folder in the System Manager object browser, and double-click the collaboration object that you want to configure.
The Configure Port dialog box opens (see Figure 5). Its default setting for type of port is Internal.
This displays the Configure Port (External) dialog box as shown Figure 6. In the Configure as area, the dialog box displays the type of port you have chosen to configure: Incoming or Outgoing.
