Blocking Outgping Caller Id On A PRI E1

I am trying to block/hide outgoing caller id on a PRI E1.

It seems that it should be fairly simple, but it is defeating me.

https://wiki.asterisk.org/wiki/display/AST/Function_CALLERID says:
“to hide your caller id, use: Set(CALLERID(num-pres)=prohib)”

That doesn’t seem to do it.

The calls are originated from AMI and I have tried a blank “CallerId:” line and “CallerId: <>“”. Neither of those made any difference.

I have also tried “hidecallerid=yes” in chan_dahdi.conf, but that has also made no difference.

I assume that I am missing something obvious?

  • Thanks David

    This line was operating with caller id withheld from a Cisco, so I am confident that it is possible to block the caller id on the line.

    If I’ve covered all the possibilities from the Asterisk end I will see if we can get the supplier to assist, but I would prefer to get it done in Asterisk.

  • Can you try

    exten => s,n,Set(CALLERID(num)=anonymous)

    in your dialplan before passing the call to the PRI?

    and/or

    exten => s,n,Set(CALLERID(name)=anonymous)

    and/or

    exten => s,n,Set(CALLERID(all)=anonymous)

    If it doesn’t work, maybe replace the “anonymous” with “” or something else.

    Sorry, no guarantee, just a shot in the dark.
