How about something like this:
  $vz(i) = 0;
  pv_unset("$vn(save_ai)")
  while ($vz(i) < $hdrc(P-Asserted-Identity)) {
      $vn(temp_holder) = $(hdr(P-Asserted-Identity)[$vz(i)]);
      if ( $(vn(temp_holder){nameaddr.uri}{uri.scheme}) =~ "^sip" ) {
            $vn(save_ai) = $vn(temp_holder);
            break;
      }
  }

  if ( $vn(save_ai) != $null ) {
        remove_hf("P-Asserted-Identity");
        append_hf("P-Asserted-Identity: $vn(save_ai)\r\n");
  }

might need some tuning, and you need the textops module.

Greetings, 

I have a client that sends me two P-Asserted-Identity headers, one with SIP URI and one with tel URI.

The pseudo variable $ai returns the topmost P-Asserted-Identity header and I only need the one with the SIP URI.

How should i proceed ? Is there a way to delete the one with tel URI? the header removal functions i find only work with header name.

I could also work with something different than $ai for this scenario.

Best Regards,
