iptables -v -L says ok but i reboot the gateway 
to be sure its not a 2.6.15 iptables problem:

tom3:~# reboot

iptraf says ok too.

where? in pwlib?

1. calls from landline over sipgate.de asterisk:

PCMA must be in first order of codec list,
since pwlib-cvs snapshot 2/7/06 ekiga error in codec handshake, ekiga tries speex 
but sipgate asterisk uses PCMA. the landline phone rings 4e4 and ekiga is in a sort of loop state then, 
the fallback or handshake retry, if any, doesnt work anymore.

2. sip:500 ekiga net:

2x ok , 1x no audio is sent out to echo test server.

cause identified: usb audio device of aiptek dv 3500 camera. 

it seems i have one more dying usb-brigde in the aiptek 3500dv camera (usb mike).
+ the usb video crashes the kernel with the spca50x driver spuriously recently.
no one can confirm it's a driver.

the last 2 years 3(!) permanently attached usb devices died here, every device within a year.
2 aiptek 1.3mega digicams and 1 megaworld x8-38u (budget saitek) joystick :(
power supply is ok (voltage, current, noise). 2 different usb mb hostchip manufacturers used in 2 years. 
cabling crosscheck'd.

wether some usb brigde-chip manufacturers have serious quality problems or the linux 
usb driver causes this degradation somehow. lately i had to rma a cheap pcmcia usb controller
(usb never worked from the start).

so i warn here and recommend everyone to only plug in cheap usb devices if theyre needed.
permanent inplug seems possibly to damage them or they degrade at use within months.
more expensive devices like canon scanners and printers i got here 
do not have this problem. either not the old creative webcam go i use know.
