[asterisk-users] Asterisk sends packets on 8004/udp

2007-10-23 Thread Yitzhak Bar Geva
For the life of me can't figure out why the Asterisk server generates an
enormous quantity of outgoing packets on port 8004/udp. They seem to have no
effect whether they are blocked by the firewall or not.
We're running SIP. Everything appears to be OK (except a large number of
ChanSpy write buffer overflow messages, which I also don't understand).
How can I discover whether these packets are desirable or not? What should I
do with them? I have found no documentation on port 8004.
Thanks in advance,
Yitzhak Bar Geva

[asterisk-users] NAT traversal packet loss measurement

2007-10-22 Thread Yitzhak Bar Geva
How can one measure the effect of NAT traversal packet loss?
We currently have no solution for NAT traversal for our SIP clients. There
is no doubt that packets are getting lost. What is not clear is how much
damage this does. On the face of it, everything seems fine. Could this be
so? Perhaps we're suffering a degradation in quality or our call setup times
could be improved. How can we measure this?
What's the simplest method of preventing packet loss due to NAT traversal in
a SIP environment?
Thanks,
Yitzhak
