[asterisk-users] INVAL Messages

[Adrian Marsh]

Hi Marian,

Thanks for the info, something I'll check into... we have recently
swapped the router over..

We receive a NEW message:

THEM   >   US    (new)

So the port forward (inbound) works ok..

We send them a reply:

THEM   <  US    (AUTHREQ)

And then they send us the INVAL...

THEM   >  US    (INVAL)

Now if any of the SRC ports got changed incorrectly, then wouldn't the
call stop completely?

This only happens some of the time, intermittently - is yours constant?

I've a Draytek 2910G router..

Hi Adrian,
	are you using this IAX thru NAT? I have this problem when i try
call 
with IAX2 and this Asterisk server is behind the NAT...

I think its here problem with UDP source port which is changed in NAT 
router, but im not sure 100%....
