[Freeswitch-users] lua trouble

[Alex]

Trying to do a lua-based bit of IVR and inexplicably struggling with 
this bit. Maybe something to do with use of variables in 
session:playAndGetDigits or possibly the regexp?

                 destnum = getDestNumber()
                 session:execute("log", "INFO User dialled "..destnum)
                 confPrompt = "say:'Now calling telephone number 
"..destnum.."'"
                 session:execute("log", "INFO Confirming with "..confPrompt)
                 confirmkey = session:playAndGetDigits(0, 1, 1, 1000, 
"#", confPrompt, "", "\\d|\\*")
                 session:execute("log", "INFO mcm.lua Number confirm 
(not) interrupted with "..confirmkey.." mcmoption="..mcmoption)
                 if confirmkey == "*" then
                         -- return to call
                         break
                 end
                 session:execute("transfer","-bleg "..destnum.." XML 
dp"..tenant_id)

The problem is with
                 confirmkey = session:playAndGetDigits(0, 1, 1, 1000, 
"#", confPrompt, "", "\\d|\\*")

It complains of "Invalid Args" (and doesn't say anything). All it has to 
do is read out the number that it's intending to call, allowing the user 
to change their mind by hitting *.
