[Asterisk-Users] iax2_read: I should never be called

[Mike Taht]

I've been testing a new asterisk server, and wondering the circumstances
that can bring on the "iax2_read: I should never be called" message.

I've been dismissing it as a network hiccough (we have two t1s with bgp
and do see them switch over once in a while, several sip users are using
comcast, there's an asterisk box connected via comcast as well), but
perhaps it could be tied to that the tdm400 board is sharing an
interrupt (and I'm trying to figure out how to get the bios not to do this)

1) would excessive interrupt latency cause iax2_read to emit that message?
2) Or a network problem? do other people see that message periodically?

any other circumstances where we might see this sort of stuff?
