Query regarding Video Media attribute in SDP in PJSIP Code

Hi,

I have attached a snapshot here for your reference.I want to hardcode below media attribute parameters in SDP in the PJSIP code.
m=audio
a=sendrecv
m=video
a=recvonly

I have made the changes in the endpoint.c file for above media details and i am able to see these media attributes in the INVITE-200 OK transmission in wireshark.(starting call from PJSIP endpoint to linphone endpoint)

But after getting the 200 OK packet at the PJSIP endpoint ,the PJSIP code modifies the attribute for video to inactive and sends an UPDATE packet to other end and i am not able to see the video at PJSIP endpoint.Now the SDP is like below.
m=audio
a=sendrecv
m=video
a=inactive

Kindly let me know the reason of this and How can i disable this update in SDP attributes to see the video at my end.

Thanks
