[OpenSER-Devel] Can't connect with RtpProxy since 1.3.X

[Iñaki Baz Castillo]

Hi, since I upgraded to SVN (now I have 2994) OpenSer fails when contacting 
RtpProxy (it worked well with OpenSer 1.2.X and same conf).
RtpProxy version is 0.3-2 of Debian Sid.



This is my related conf:

  modparam("nathelper", "received_avp", "$avp(i:42)")
  modparam("nathelper", "sipping_method", "OPTIONS")
  modparam("nathelper", "natping_interval", 20)
  modparam("nathelper", "ping_nated_only", 1)
  modparam("nathelper", "sipping_bflag", 7)
  modparam("nathelper", "sipping_from", "sip:openser at openser.domain.org")
  modparam("nathelper", "rtpproxy_sock", "udp:localhost:22222")


RtpProxy runs as:

  ~# rtpproxy -f -l 0.0.0.0 -s udp:127.0.0.1:22222

(in foreground mode in order to debug but I've tryed too to run in background, 
in different machines, etc).



I restart OpenSer and get:

  ERROR:nathelper:send_rtpp_command: can't send command to a RTP proxy
  ERROR:nathelper:send_rtpp_command: proxy <udp:localhost:22222> does not
    respond, disable it
  WARNING:nathelper:rtpp_test: can't get version of the RTP proxy
  WARNING:nathelper:rtpp_test: support for RTP proxy <udp:localhost:22222>
    has been disabled temporarily




RtpProxy says (it receives connection from OpenSer!!):

  received command "1886_0 V"
  sending reply "1886_0 20040107

  ...




I've tryed everything and can't get it working. I've read the devel doc for 
nathelper module and see no notable changes.

Please, can anyone confirm he has OpenSer 1.3 working with RtpProxy?
Could it be a bug?


Best regards.
