[asterisk-tech] asterisk DoS ?

[HILL David]

I had something similar ages ago. Check that you are not loading the
TDMoE driver, it generates 2Mb/s of consistent traffic on the Ethernet
and causes Asterisk to get itself confused. So to do this make sure that
there is no eth in /etc/zaptel.conf and do a lsmod | grep zaptel and
make sure that ztd_eth is not loaded. If it is then unload it and see
how it goes.

Hey all

I've been having issues with asterisk and I dont know where else to
look. It seems like a DoS attack.

Setup:
Debian Linux
asterisk 1.2.15
zaptel 1.2.13
1 TDM board with 2 fxo modules and 2 incoming lines.
3 Snom 300 phones on network.

Problem:
when a user tries to dial, they get a constant distorted noise. They
cannot dial out with the phones. When I log in to the CLI I can dial
out using the dial command. I've changed the bindaddress in sip.conf
to the static server name, but that does not seem to help. It seems
like the sip phones are flooding the network.

I'm out of options here. Can someone please point me in the right
direction.

TIA
