hello, all of users:
i try to use sipp to send rtp g729.pcap to asterisk server. i can see some info 
shown rtp packages have been sent from sipp screen, but when i use wireshark to 
get it, the rtp g729 is empty. i am confused for that. anyone can tell me:
1) how do i capture g729 codecs use tcpdump :

tcpdump -T rtp -vvv dst 192.168.2.127 -w g729.pcap // i want to get g729 codecs
from my Xlite(192.168.2.111 and supported G729), is it correct?
2) if i use wireshark to capture rtp with g729only, 
how do i write the filter?
because i suspect my g729.pcap is wrong, that's why it is empty.
anyone has an idea for that, please give me some hints.
thanks!
lizhong
