I don't know what RTCP keep alive is, but if they just mean to turn on RTCP, you can do it with the following params in your sofia configuration:
 <!-- enable rtcp on every channel also can be done per leg basis 

      with rtcp_audio_interval_msec variable set to passthru to pass 
      it across a call -->
 <param name="rtcp-audio-interval-msec" value="5000"/>
or, set the rtcp_audio_interval_msec channel variable.
