Check why the attribute line in SDP of 200 ok "a=rtpmap:0 PCMU/8000/1" is before the media line " m=audio 16000 /RTP/AVP 0 101". This might have made the phone to treat the SDP as Bad SDP in 200 OK.
This is one limitation of SIP where the caller cannot tell why it did not like the SDP. May be the Bye Reason header can be used to indicate these type of problems.
