[Asterisk-Users] Noise over iax2 and FXO

[Paulo Mannheimer]

Hi,

I have an installation connecting two machines through IAX2. Each
machine has 3 FXS and 4 FXO ports.

Everything seems to work fine, except on one FXO port, where I
constantly get a strange "locomotive" noise when I use it to terminate
an IAX2 incomming call. Usually after a while the strange noise goes
away, but it is very annoying.

Any hints on what can be causing this?

Thanks!
