Comment (by taliho):

 Looks that the server is actually responding that it's using UDP.

 To use TCP it would need to reply with something like:
 Transport: RTP/AVP/TCP;interleaved=0-1

 But the reply is:
 'Transport:
 RTP/AVP;unicast;destination=192.168.0.106;source=192.168.0.105;

 which is interpreted as UDP:
