Hi,

I have a SIP Trunk account. From some companys that call me, which also have a SIP Trunk account, I can only see the main number in the phone display but not the extension. The correct number with the right extension is only inside the sip_P-Asserted-Identity variable and not the caller_id_number.

So I thought I could assign the sip_P-Asserted-Identity to effective_caller_id_number and all is fine but that is not working.

conf/dialplan/public/voip_inbound.xml

<extension name="telekom-voip-inbound-extension">
   <condition field="${sip_h_P-Called-Party-ID}" expression="(XXXXXXX(\d{2}))">
      <action application="set" data="domain_name=$${domain}"/>
      <action application="set" data="effective_caller_id_number=${sip_P-Asserted-Identity}"/>
      <action application="set" data="effective_caller_id_name=${sip_P-Asserted-Identity}"/>
       <action application="transfer" data="$2 XML default"/>
   </condition>
</extension>

What am I doing wrong?

Best regards
