WIP: How to shutdown the GPRS session?

What is the recommended approach to close-down a GPRS session with WIP?

All the samples just show wip_close() - which closes the socket-level “channel”, but seems to leave the GPRS session (the Bearer) active…

There are wip_bearerStop() and a wip_bearerClose() commands, properly documented in the user guide. GPRS is a bearer like any other.
