---------------------------------------------------------------------- 
I try to implement this patch using a asterisk 1.4.22.2 and libpri 1.4.7 ,
i rewrite the patch to apply on my version of asterisk and libpri, and
apply the changes on channel_zap.c 

On my dialplan when i do a NoOp(PRIREVERSECHARGE => ${PRIREVERSECHARGE}) i
dont get any result ( nor 0 nor 1)

Block collect calls on Brazil is very important because some telco dont do
the block, so we have a problem with this.

Below a part of pri debug that show the charging indication (with the
patch)

< [4a 01 81]
< Reverse Charging Indication (len=03): 1

on cli i get

    -- Executing [9700 at embratel:4] NoOp("Zap/80-1", "CALLERID =>
XXXXXXXXXX") in new stack
    -- Executing [9700 at embratel:5] NoOp("Zap/80-1", "PRIREVERSECHARGE =>
") in new stack


and on my extension.conf i put this

exten => _97[0-4][0-9],n,NoOp(CALLERID => ${CALLERID(num)})
exten => _97[0-4][0-9],n,NoOp(PRIREVERSECHARGE => ${PRIREVERSECHARGE})


some minutes ago i try to do a diferent implementation on chan_zap.c

i try this

if (e->ring.reversecharge){
      pbx_builtin_setvar_helper(c, "PRIREVERSECHARGE", "1");
} else {
      pbx_builtin_setvar_helper(c, "PRIREVERSECHARGE", "0");
}

but i cant get any result on my dialplan


My asterisk is a modified version with openr2 patch too
