Summary:                    Read() does not set variable
Description: 
When Read()ing dtmf input, although the debugging 
console shows what the user entered the variable 
is left unset.  For example, this code from the 
documentation does not work:

exten => s,1,Gotoif($[ "${LEN(${extensao})}" < "3"]?3:100)
exten => s,n,NoOp(executando - ${extensao} - )
exten => s,n,Read(digito||1)
exten => s,n,SayDigits(${digito})
exten => s,n,Set(extensao=${extensao}${digito})
exten => s,n,GoTo(s,1)
exten => s,100,GoTo(from-pstn,s,1)
exten => h,1,hangup()

SayDigits says nothing because ${digito} is empty 
regardless of what the user presses.

---------------------------------------------------------------------- 
The issue at hand, the fact that Read was not populating the variable, has
been identified as being the use of pipes instead of commas. I have
confirmed by making a sample dialplan that used pipes that the issue the
reporter mentions happens.

As far as the comma and pipe usage goes, it is documented in UPGRADE.txt
in the Asterisk source directory of 1.6.0. That document is the place to
look to find behavior changes and application syntax changes when upgrading
major versions of Asterisk.

Anyway, as far as backwards-compatibility of applications goes, this
really isn't the proper forum for this sort of discussion. I'm not trying
to blow off your point, but we've been hearing about this more and more the
past few months and so our future efforts when changing the code is to
preserve backwards-compatibility of old applications if at all possible. As
far as changing things which were removed with the 1.2 or 1.4 releases
goes, that's a different matter.

Anyway, since the issue reported here has been identified and no fix is
necessary, I'm going to go ahead and close this issue.
