call forwarding issue with anonymous (Blocked Caller ID)

[RCCradio]

Our setup:
Someone calls in on a number +1 (555) 555-0826, which gets forwarded to an answering service +1 (555) 555-6211. I have a dial plan set-up that when someone calls in it forwards to 982615555556211. The dial plan strips the prefix "9826", and sets the 'effective_caller_id_name" and "effective_caller_id_number" to 15555550826. This was the answering service knows what company the person is calling. Everything works until someone with a anonymous, or blocked caller ID, calls. When they call the Caller ID is blocked when the call is forwarded. I've tried using the "action unset sip_h_Privacy", "action unset sip_h_Privacy=id", "action unset sip_h_Privacy=none", "action set sip_h_Privacy=id", and "action set sip_h_Privacy=none". I've also tried using the "outbound_caller_id_name" and "outbound_caller_id_number", but nothing seems to work to turn off the blocked caller id.

check this thread. There is a very specific order in which you need to do things otherwose it doesn't seem to work.

@Adrian Fretwell You nailed it! The order was very important. I tried those commands before and they must've been in a different order. But this finally unset the header and I'm able to call the door bell!!!!

  <action application="set" data="sip_cid_type=none"/>
  <action application="unset" data="sip_h_Privacy"/>

Thank you for this. I tried it and at first it didn't work.
I had to add the

<action application="privacy" data="no"/>

<extension name="Telnyx.9826d11" continue="false" uuid="XXXX">
    <condition field="${user_exists}" expression="false"/>
    <condition field="destination_number" expression="^9826(\d{11})$">
        <action application="set" data="sip_h_accountcode=${accountcode}"/>
        <action application="set" data="sip_cid_type=none"/>
        <action application="unset" data="sip_h_Privacy"/>
        <action application="privacy" data="no"/>
        <action application="export" data="call_direction=outbound" inline="true"/>
        <action application="unset" data="call_timeout"/>
        <action application="set" data="hangup_after_bridge=true"/>
        <action application="set" data="effective_caller_id_name=15555550826"/>
        <action application="set" data="effective_caller_id_number=15555550826"/>
        <action application="set" data="inherit_codec=true"/>
        <action application="set" data="ignore_display_updates=true"/>
        <action application="set" data="callee_id_number=$1"/>
        <action application="set" data="continue_on_fail=1,2,3,6,18,21,27,28,31,34,38,41,42,44,58,88,111,403,501,602,607,809"/>
        <action application="set" data="outbound_caller_id_name=15555550826"/>
        <action application="set" data="outbound_caller_id_number=15555550826"/>
        <action application="set" data="outbound_prefix=9826"/>
        <action application="bridge" data="sofia/gateway/XXXXXX/$1"/>
    </condition>
</extension>

Very good to know. Thanks for sharing

Well found an issue, I spelt privacy wrong. It's updated in the post now. This was causing the calls to show as failed in the call history and not getting recorded. The calls still forwarded correctly.
