Hello Sebastian,

In your case the local phone/ATA is the leg B right?
With that settings you get transparency between the two legs?
How ${sip_from_user} is defined?

Hello Igor,

Thanks for posting this. I find this an interesting question, too.

I use this currently on the leg to my local phone and ATA:

  <extension name="cli-handling" continue="true">
      <action application="export"
      <action application="export"
      <action application="export" data="_nolocal_sip_cid_type=none"/>

When there is a "clip no screening" call coming my way, I also get both
numbers, the calling party in PAI and the generic number in From, from the

I didn't bother looking further into this because I actually don't know
which number the phone/ATA would display if they received both numbers.
Maybe they are not aware of "clip no screening", which wouldn't be a
surprise because this feature is not supported in all countries (I think in
the US they don't support it).

Kind regards,
