[Freeswitch-users] how to force a MINIMUM call duration

[Frank @ Impact]

On our last bill, the carrier said we had 27% short duration calls
(maybe they are wrong but it was on the bill).  It is definitely not
call center. But these callers hangup as soon as they hear answer
machine or most of the time a ring back tone from cell phone.  This
class of caller will call a cell phone, hear the ring back, hangup right
away and then call back another 2 minutes later and repeat the cycle.
 
So, if I have to make it work the way I suggested (hold the connection
open for at least the minimum time, how might you suggest I do it in the
dial plan?

Don't want the tone to be wrong here, but this makes no sense. Carriers
surcharge like this precisely to guard against call center, predictive
and other mass outbound calling scenarios.
 
It just doesn't make since, math wise, that individuals hanging up on
voice mail are going to significantly impact overall ACD stats, etc. So
unless you have a very strange set of use cases or are pushing another
category of traffic (ie call center) that skews you overall relationship
with the carrier - I would go back and re-negotiate your arrangement.
 
Yes, FS is a b2bua and all is possible. But it is probably a better use
of time to approach this as a business issue.
 
My 2 cents.

We have a carrier that penalizes us with a surcharge for short duration
calls (sound familiar?).
 
So when a FS caller (not a call center or predictive dialer) calls a
cell phone and gets a ring tone or calls an answering machine, the FS
caller hangs up because they do not want to leave a message.  But they
do this in less then a few seconds after the call is answered.  This
becomes a short duration call and bang the surcharge applies.  It is
actually cheaper to pay for a longer call time (6 seconds in this case)
and avoid the short duration surcharge.  But the FS caller does not know
this.
 
So, how can FS hold the connection to the called party open for at least
the minimum amount of time I need to avoid the short call charge. even
though my FS caller has already hung up the phone on his end?  I would
like to do this in the xml dialplanif possible.
 
Thanks
