  Release Summary for 4.3-25
  [![Generic badge](https://img.shields.io/badge/release_status-building-lightgrey.svg)](https://shields.io/)
  Changes to branch `4.3` after version `4.3.24`.
  * [override 480 if call is progress](https://github.com/2600hz/kazoo-configs-kamailio/commit/001f55c6b2b8aa3ecf30853d86a64c73b0847c8f) - _by lazedo_
      * FLAG_SESSION_PROGRESS is set when
      the media server sends a 180/183
      which is triggered after a route reply.
      if there are no endpoints to bridge
      to (dnd, faulty callflow) the return code
      from the media can be 480 if not set explicitly by
      callflow action. in that case
      we were passing it to the incoming leg
      carrier/endpoint and some carriers retry
      the call which we don&#039;t want.
