Hi,<BR>
<BR>
I currently have a problem with one way audio or no audio at all on some calls between a Snom and an XLite client. Both are on different networks.<BR>
<BR>
I am using nathelper to resolve natting issues with SIP packets and MediaProxy for all calls using:<BR>
<BR>
engage_media_proxy();<BR>
<BR>
It looks like the media proxy is engaged, but not passing the audio on, I've set the following in /etc/sysctl.conf:<BR>
<BR>
net.ipv4.conf.default.rp_filter=0<BR>net.ipv4.conf.all.rp_filter=0<BR>#net.ipv4.tcp_syncookies=1<BR>
net.ipv4.ip_forward=1<BR>net.ipv4.conf.default.forwarding=1<BR>net.ipv4.conf.all.forwarding=1<BR>
# Uncomment the next line to enable packet forwarding for IPv6<BR>net.ipv6.conf.all.forwarding=1<BR>
# Do not accept IP source route packets (we are not a router)<BR>#net.ipv4.conf.all.accept_source_route = 1<BR>#net.ipv6.conf.all.accept_source_route = 1<BR>#<BR># Log Martian Packets<BR>#net.ipv4.conf.all.log_martians = 1<BR>
<BR>
The test server is using Ubuntu 9, is there anything above that looks incorrect? Firewall logs do not show any traffic being blocked either.<BR>
<BR>
Any advice would be appreciated.<BR>
<BR>
Thanks,<BR>
<BR>
