Hi Fellows I want to implement the handover (Wi-Fi <-> WiMAX)) using PJSUA (pjsip 2.0). setup is simple ..Running Vidgui application on two PCs (laptop (user1) with two interfaces (Wi-Fi/WiMax) and the other PC (user 2) to receive a call.) user1 calls to user2 ..call has been answered setup and both parties can see each others video. user 1 laptop switching the network interface every 10 sec I was thinking to implement handover using re-invite to communicate changes of IP addresses, renegotiating SDP, etc. But before that i checked what if i don't communicate any changes to the reciever..what will happen? To my surprise, pjsip seems to not care of the change of IP address and i have found that such changes are not needed to be communicated to the other party. (I am just add/change routes in the win 7 routing table to prefer one network interface over other). vidgui application has not affected by the change of network interfaces and video is working fine between two sides i.e., without sending any re-invites or state changes? What is happening? Does PJMedia takes care of change of network interface? Is there something happening by RTP/RTCP sender report/ receiver reports ? How? [video quality is satisfactory at the user2 while the user1 (performing handover) video quality is very poor] Do I really need to implement handover using SIP messaging or pjSIP taking care of this is equally good? I would really appreciate your kind suggestions. Thank You. Profound Regards Akmal -------------- next part -------------- An HTML attachment was scrubbed...
