asterisk users - Jul 2010 - chan_iax2: I should never be called!

Hi,

Recently, one of my Asterisk servers stopped connecting calls and required a
reboot to "fix it" (did not try to restart or reload).

The log showed loads of this message:

NOTICE[302] chan_iax2.c: I should never be called!

This highly repeated message seems to be preceded by something like:

WARNING[10767] channel.c: Exceptionally long voice queue length queuing to
IAX2/coinbound-15879

When this happens it also seems that SIP peers on a gigabit LAN start going
on/offline frequently. So that seems to explain why calls start to fail. There
is absolutely nothing wrong with the network (and switches). I don't know if
it can be a NIC problem on the server but how can I tell?

Rebooting the server solved everything... for now...

Any ideas?

Hi all,

i have a beginners question. How are SIP calls and IAX2 calls processed by
Asterisk over the network?
What i mean is, is there a permanent connection required between the Asterisk
Server and the clients or is the Asterisk Server only involved for lets call it
the "routing"?
