    <tt>Hi,<br>
      <br>
      You may have 2 cases, not sure which is yours:<br>
      <br>
      1) the 2 media sessions are in parallel in the same calls (you can
      have 2 -or more- RTP streams in the same SIP session). In this
      case, RTPproxy will take care automatically of each RTP stream)<br>
      <br>
      2) you have first one audio stream which is replaced by another
      FAX stream, via a re-INVITE - in this case, if you the normal
      offer / answer for RTPproxy also for the re-INVITE, it should be
      ok.<br>
      <br>
      Regards,<br>
    </tt>
