Guys, I'm having problems in the fading voice calls, receptive and active, that in SIP accounts. While few people using the system, calls are perfect, but it beats the normal use of connections (average 30 concurrent), the voice begins to fade from people. Soon I figured some network problem, I did a tcpdump and analyzed by wireshark ...the strange thing is this ... all packets that arrive on the server asterisk are normal or jitter, latency ... But whenAsterisk sends packets to the network or the ISP ... maggoty packages are ... jitter of150ms on average ... latency of more than 1000 ms ... That is, by the way is not the network itself, but the network on the machine ... Dropped iptables to make sure no influence ... I changed the network card and cables... did nothing more ... Anyone have any ideas to help me and chase to find the problem? PS: The server is a CentOS 5.5 - 32 bit ... I've tested the 64bit tb but with the sameerror ... thanks, -------------- next part -------------- An HTML attachment was scrubbed...

I have a similar issue; albeit different.
I have only one device that is experiencing fading issues. They are a remote
office on a DSL line.
At first I thought it was a network bottleneck issue but they only max 800k
of their 3meg line.
What TCP command can you run to just capture all relevant information from
that one IP device?
What particulars should I be looking at?
All current logs and resources show nothing!

Subject: Re: [asterisk-users] Res: Fading voice problem
Are you trunking the calls via IAX2 or something?
Are you using a jitter buffer?
Are you sure about the direction?
Do you get the same problem if you use something like sipp to create 30
LAN calls and one Internet call?
