    <p>Hello,</p>
    <p>if you get a core dump, then send the backtrace taken with gdb --
      even better, open an issue on the bugtracker from
      github.com/kamailio/kamailio - the template there should guide you
      on what details to provide.</p>
    <p>On the other hand, can you just try with:</p>
    <p> xlog("L_INFO","route(fixdigits)  @@ $rm - E164 :
      <a class="moz-txt-link-freetext" href="sip:$(fU">sip:$(fU</a>{s.substr,1,0})@$fd");</p>
    <p>So no need of string concatenation with +, the variables inside
      the parameter for xlog() are evaluated always.<br>
    </p>
    <p>Using expressions for parameters was something added by SER
      branch in the past, not sure if all modules are handling that
      properly.</p>
    <p>Cheers,<br>
      Daniel<br>
