    Do not delete the sesssion.  Simply answer/offer again.  RTPengine
    will update the monologues.  The session is still the same dialog so
    don't delete it.  I am using RTPengine and have no issues with
    re-invites.<br>

      <p>Hello</p>
      <p>I am not sure if that is a feature that has to be implemented
        or a feature that is not working.</p>
      <p>I am using RTPEngine for RTP handling on a mhomed environment.
        Initialy I was tried to use the rtpengine_manage which didn't
        work for me so now I am using offer, delete and answer.</p>
      <p>The problem I have now is when the carrier or customer sends
        re-invite to renegotiate codecs in fax transmission. How should
        I handle such case? If not handled, carrier's Public RTP IP is
        passed to the internal interface back to customers on the
        internal network and the OK coming from customer to OpenSIPs
        with the Internal SDP of the customer, is forwarded as it is to
        the carrier.</p>
      <p>Thank you for your help</p>
