[OpenSER-Users] Working in TCP but NOT in UDP?

[David Villasmil Govea]

Hello all,

     I've got a working conf on which RTPs work perfectly with TCP, but
fails to work with UDP... can anyont tell me why??

Here's my conf:


#
# sample config file to be used with nathelper/rtpproxy
#
# start RTPProxy with: rtpproxy -l your_public_ip -s udp:localhost:8899
#

# ----------- global configuration parameters ------------------------

fork=yes
log_stderror=yes    # (cmd line: -E)

/* Uncomment these lines to enter debugging mode
fork=no
log_stderror=yes
*/

check_via=no    # (cmd. line: -v)
dns=no          # (cmd. line: -r)
rev_dns=no      # (cmd. line: -R)
