Hello Greger, Thanks for your ideas, however all SIP messages are ok, including SDP line as you mentioned. There is no firewall blocking UDP>1000 infront of mediaproxy. The situation is actually that mediaproxy dont relay RTP packets. Both clients send their packets to mediaproxy to the ports specified in the RDP line, I can detect them with ngrep. Also there is no error from the dispatcher since it is not used. Mediaproxy and SER sits on the same machine... I tried using the dispatcher but got the same result as without it. It must be a configuration issue with mediaproxy, because when I used the mediaproxy sample ser.cfg it worked quite nicely. However that was on a previous verison of SER and mediaproxy 1.3.1. Also SIP conversation is good between SER and clients. It seems there is a problem in the communication between ser and mediaproxy. Mediaproxy just listen but do not send... There are sadly enough no entries in the log that relates to this issue... Any more ideas? Or anybody else? -----Ursprungligt meddelande----- Från: Greger V.

DoS protection that kicks in (lots of small UDP packets). I know Zyxel will do that sometimes. Could also be a problem in the setup of your clients. Do they find a common codec? Look in /var/log/messages for errors from proxydispatcher or mediaproxy. You could have a problem with the communication. Check the INVITE from ser to callee and the OK from callee to caller. Both should have an SDP line with m= and then the IP address of your mediaproxy. g-) Roger Lewau wrote: > Hello list... > > I've installed SER 0.9.0 and mediaproxy 1.2.1 and dowloaded the > getting started scripts (issue 04a) from onsip.org. > Setup everything as instructed, added a couple of users to the > database and tried to setup a call between one public and one NATed > UA. > Both phones register properly and signalling seems to be working > fine, I ring each device from the other, problem is there is no > sound. > > So I checked the mediaproxy sessions... and it looks like this > > > Caller Via Called > Status Duration Codec Type Traffic > --------------------------------------------------------------------- > - > ------ > ---------------------------------- > 82.182.194.x:5004 - 212.247.91.x:35014 - 82.182.194.x:49160 inactive > 0'07" Unknown Audio 0/0/0 > > Total traffic: 0bps/0bps/0bps (in1/in2/out) Session count: 1 > > I dont really understand the output but I think "inactive" as well as > "Unknown Audio" is not a good sign. > > How ever, I then used Ngrep to see if there are some rtp traffic > going on and sure enough, there is traffic comming in from both UAs > but no traffic is leaving the proxy.
