[kamailio/kamailio] Play media when Kamailio+rtpengine are as an end point(not proxy) (#2315)

by bshirazi

### Description  With rtpengine module play_media function it is possible to play media to one of the endpoints(Kamailio is normal proxy) but I like to use Kamailio+rtpengine as an end point playing music for caller(simple media server). ### Expected behavior Possible to use Kamailio+rtpengine as an end point playing media. ### Possible Solutions I see some efforts in mailing list trying to build/generate a 183 response inside script to simulate a dummy end point and then use rtpengine_play_media function.
