I'm replying here to a mail sent privately by Fan to me:

sofia-sip doesn't manage the media *at all*, you have to provide a
media subsystem to your own application as sofsip_cli does using
libgstreamer to provide the media framework.
I suggest you to study the code of sofsip_cli and look at how the
problem is addressed there, then eventually post here questions if you
need some help.
Regards.
