The problem will be that your friends capture probably has not seen the the related SIP or RTSP control packets associated with the conversation. RTP runs on top of UDP, but is doesn't use a fixed or well known port, so it is difficult for Wireshark to always determine whether particular UDP packets are UDP. If you right-click on a UDP packet that you think is RTP and use "Decode As..." to select RTP, you should get the result you are after.

 Hi!
 
  I am running a test using wireshark running on two laptops located on different location of the world.
 
  The wireshark running on my laptop can capture the RTP traffic but wireshark running on my friends laptop cannot capture the RTP traffic and only UDP.
 
  This is quite strange. Why wireshark dont capture the RTP packets on my friends laptop?
