I still can't get into the SDP in early media response:

The sip pointer in the nua_r_invite 180 is nil. And as someone suggested
that I can get into the SDP in state change but still I get into it. Any
suggestion?

Attached is the log in the early media situation. The SDP is showing in
the 180 Ringing message but I don't know how to get into it.


Regards!
