Please ignore my previous response. I triple looked into the sniffing and I
am not a expert in this. What i can see is that the Tunnel server sending
out of order sequence number on the same SSRC caused mediaproxy to change
port. 

64.x.x.x is tunnel sever, 74.x.x.x is mediaproxy, 54.x.x.x is asterisk. 

64.x.x.x tunnel server send seq 4 and 5 to Mediaproxy on the same 40061 src
and 1136 dst port  
74.x.x.x mediaproxy send seq 4 to asterisk on the same 1138 src and 13746
dst port 
74.x.x.x mediaproxy send seq 5 to asterisk on a different src port 1024 and
13746 dst port
54.x.x.x asterisk sent seq 53534 to mediaproxy on src port 13746 and dst
port 1024
