[asterisk-users] Stripping characters from ${CALLERID(num)} ?

[Faisal Hanif]

Use Filter command in dia-plan to get numeric only string,

Set(MYNEWCLI=${FILTER(0123456789,${CALLERID(number)})

Subject: [asterisk-users] Stripping characters from ${CALLERID(num)} ?

Greetings-

On occasion, I have calls coming into an Asterisk 1.2.x system where the
${CALLERID(num)} includes '-'. Ex:

123-456-7890

How can I strip the dashes from the number, leaving me with '1234567890'?

I've tried the following which does not appear to be working:

Dialplan:
exten => _X.,n,Set(PROPERCID=System(echo ${CALLERID(num)} | sed s/\-//g))
exten => _X.,n,NoOp(Fixed proper CID is ${PROPERCID}

Console Output:
    -- Executing [1111111111 at cidmangletest:4] Set("SIP/w.x.y.z-b4d55ce8",
"PROPERCID=System(echo 123-456-7890 | sed s/\-//g)")
    -- Executing [1111111111 at cidmangletest:5] NoOp("SIP/w.x.y.z-b4d55ce8",
"Fixed proper CID is System(echo 123-456-7890 | sed s/-//g)")

Obviously, I'm trying to throw the CID through sed via System() to strip the
dashes. Can anyone explain how to accomplish this? Or even better yet, how
to strip the dashes directly in the dialplan without the use of System()?

Thanks!
