[Asterisk-Dev] IAX2: "INVAL" packets?

[Stephen Davies]

Hi,

Been making some calls out via Jerjer's Nufone service on IAX2.

Calls are suddenly dropping - I put IAX2 debug on and it seems to
relate to receiving an "INVAL"

I can see that chan_iax2.c drops the call like a hot potato[e] if it
receives an INVAL.  But what's the problem?

I append a chunk of the log.

Thanks,
Steve
