asterisk users - Feb 2012 - externip nat audio sip trunk issue problem

Hi all,

  I've tried search this problem on the list... no luck...

  The case is:

without externip/localnet config on sip.conf [general] my SIP trunk works,
but with no audio NAT problem (asterisk sends the private 192 address to
the outside...)

when I configure externip/localnet correctly my SIP trunk simply disappear!
Checking the signalling with tcpdump shows me that Im sending the packets
to the correct SIP trunk IP but there is no response AT ALL from it...

Anyone had this problem?

Thanks,
Gabriel

Can you explain this?
What do you mean no response? Is it registering? Do you have a debug output?

Use tcpdump -v (or wireshark) to look at the SIP packet contents as well 
as the IP headers.  If possible, do this on the external interface of 
your firewall to see what's getting sent out to your peer.  See if the 
values all appear to be sane.

Compare the SIP session contents of packets with externip configured and 
packets without that setting.
