hi,
"User Datagram Protocol, Src Port: 39409 (39409), Dst Port: 13429 (13429)"
copy from asterisk 11 rtp.conf
rtpstart=10000
rtpend=20000
have you changed port range? if no then
your client sending rtp to a port higher then configured in rtp port range
and asterisk ignore that port.
try to change rtpend=30000 or if there is option in softphone restrict it
to use same range as in rtp.conf.
let me know if this solve you problem.
