It looks like in some cases people are using Flash/Recall as a
failover/logic pattern in some Voip setups.
It seems, from my knowledge of voip setups and a quick ask around, that
using flash/recall you can force the PABX to switch to a physical line,
rather than using a SIP connection out from the PABX. That is, in the above
example, that dialing with the "f" at the end would denote that this should
be carried over a copper/digital line rather than a protocol line.
