Hi,

First, thanks for red5phone, it's amazing !!! nice job !!!

I've got an ubuntu server with a standalone SIP red5phone. It's working !!


The sound from flash isn't good, how can I improve it ? (I've tried to put 44 in flex and 44000 in sip.cfg without any success, maybe I've to change audio_frame_size too ?). I think I need to edit java sources but where :/

 

 

Thanks a lot

 

 

 

 

To make it works under ubuntu :


(This is my installation on a clean Ubuntu 8.04 server)

 

apt-get install sun-java6-jre

 

cd /usr/src

 


wget http://www.red5.fr/release/0.7.0/debian/red5_0.7.0_all.deb

dpkg -i red5_0.7.0_all.deb

# or apt-get install sun-java5-jre red5


wget http://red5.4ng.net/red5.jar
wget http://red5.4ng.net/sip.zip
unzip sip.zip


cd /usr/lib/red5


mv red5.jar red5origin.jar
cp red5.sh red5origin.sh
cp /usr/src/red5.jar red5.jar
chmod 777 red5.jar
nano red5.sh


#put it :
exec $JAVA -Djava.security.manager -Djava.security.policy=conf/red5.policy -cp red5.jar:conf:$CLASSPATH:lib/jetty-6.1.7.jar:lib/jetty-util-6.1.7.jar:lib/jetty -xbean-6.1.7.jar org.red5.server.Standalone
#end


mv /usr/src/sip ./webapps/sip

./red5.sh to start the server ...

#if you have a problem with sip.cfg, just copy it to /usr/webapps/sip
