[asterisk-users] Logical AND (resent due to bounces)

[Adrian Marsh]

Hi All,

 

I'm trying to figure out why in the below code, the PSTN_NUM variable is
always amended

 

exten => s,n,NoOp(${PSTN_NUM})
exten => s,n,ExecIf( $[ "${PSTN_NUM:0:1}" != "0" ] & $[
${LEN(${PSTN_NUM})} = 10 ]|Set|PSTN_NUM=001${PSTN_NUM})
exten => s,n,NoOp(${PSTN_NUM})

 

-- Executing [s at macro-setpstncli:8] NoOp("SIP/427-b7d0f518",
"0123456789") in new stack
    -- Executing [s at macro-setpstncli:9] ExecIf("SIP/427-b7d0f518", " 0 &
1|Set|PSTN_NUM=0010123456789") in new stack
    -- Executing [s at macro-setpstncli:10] NoOp("SIP/427-b7d0f518",
"0010123456789") in new stack

 

It should evaluate PSTN_NUM and add a 001 only if: PSTN_NUM is 10 digits
long and doesn't start with a 0.

 

However, from the debug it's being changed, even though the first test
operator logically is 0.  If seems as though the "&" isnt being applied.

 

Any ideas?

 

Thanks

 

Adrian
