[Freeswitch-users] Remote pickup of on-hold extensions

I've thought about those options... the obstacle is mostly the users, who
aren't the most trainable people in the world, and they're used to the
present key system which allows them to have pretty colored buttons that
they only press once. I dread the attempt to explain the concept of
transferring a call, and the question will inevitably come back: "Why
can't we have line keys like the last system?" Calls will likely get lost
or dropped, and of course, the system gets blamed ;-)

The other option, again if possible, is to program a soft key as a
one-touch "Park" key that announces the park extension number, which could
also be assigned to a BLF, then parks the call. Then we have one touch
park, one touch retrieve.

I have to sell this to them in such a way that it doesn't come across as a
feature downgrade, or we may end up stuck with the present system until it
dies and no inter-branch connectivity.

I suppose it's the same old predicament... things would be so simple if
management just said yes :)
