asterisk users - Feb 2012 - Is there any way to make call fail after # of rings?

My customer needs to set a forwarding based on number of rings,i.e.,
if the phone rings 5 times (user-selectable), then try another number.
Is there a way to do such a thing with Asterisk? I could not find way
to do it based on the documentation of the Dial function. The protocol
is SIP only, however, I could use a different one if it provided a
workaround. If this is the wrong tool for the job, what technology
would do this?

'Phone rings' are not a standard unit of measurement. Is there a problem
with defining the time in seconds? If not then Dial can do this for you.

Simply, without checking for BUSY, DND or TIMEOUT
I'm assuming each ring period is 3 seconds.

exten => 8512,1,Dial(SIP/8512,15)
exten => 8512,n,Dial(DAHDI/GO/101233456,15)

Or another way.

Maybe the FollowMe application, allow multiple numbers to be tried, each
after a configured timeout.

from followme.conf

[default]
musicclass=>default
; The moh class that should be used for the caller while they are waiting to
be connected.
context=>default
; The context to dial the numbers from
number=>01233456,25
; The a follow-me number to call. The format is:
; number=> <number to call[&2nd #[&3rd #]]> [, <timeout
value in seconds> [,
<order in follow-m
   Numebr

Thus followme 
number=>8512,15      ; try local extension for 15 seconds
number=>101233456,15 ; then try outside number for 15

Try this

exten=> yournumberhere,1,Dial(SIP/peern1,60)

exten=>  yournumberhere,n,GotoIf($["${DIALSTATUS}" !=
"ANSWER"]?4)

exten=>  yournumberhere,n,Hangup

exten=> yournumberhere,n,Dial(SIP/peer2,60)

exten=>  yournumberhere,n,GotoIf($["${DIALSTATUS}" !=
"ANSWER"]?9)

exten=>  yournumberhere,n,Hangup

you can add more conditions in the same way

You have to do it by timing, not by number of rings.  Asterisk simply
doesn't
know how long each "ring, ring, pause" cycle takes  (it's a
configurable
property, and only analogue phones on an FXS port can be trusted to honour it 
anyway).

If one ringing cycle takes 3 seconds, then 5 rings would be 15 seconds. So 
just use something like
Dial(SIP/${EXTEN},15)
in your dialplan.

If the call was not answered, then the step number will get an extra 100 added 
to it. So, if your Dial() command was at step 2, it will move on to step 3 if 
the call was answered and hung up; or step 103 if the line was busy or timeout 
occurred.

Hope that makes sense.
