Can you also verify the following for issues where transfers do not work:
* Make sure the following are defined for the post-route number the agent is transferring to:
Dialed number plan
dialed number
call type
script
Make sure post-routing is enabled on the CVP PG in PG explorer under the Peripheral tab
Make sure NetworkTransferEnabled variable is set to 1 in the ICM script that occurred *before* the post routing script. It is important to note that the NetworkTransferEnabled variable applies to *future* transfers, so it must be set in the script before the post-route. If the agent is going to do more post-routes, it must also be set at the beginning of the current post-route script.
