asterisk users - May 2005 - Good NAT Pnp Hardphone

Hello All,
I am looking for a sip phone that is capable of automatic nat.  The
Cisco ata186 for example works fine for natting with iconnecthere, but
as for asterisk, both my 7960 and polycom ip600 require you to set the
nat ip on the tftp.

Does anyone know a good phone (or ata) that can do this automatically?

For example,
I want to give a phone to my brother, who is going to europe.  His ICH
softphone is fine there.  Both the poly and cisco though require you to
setup for nat.  He would not be able to set this up though, so I want to
just give him a preconfig'ed phone and plug and go... 

Any ideas?

Greg

My experience with the Sipura SPA-841 is that, as long as you set up the
STUN server and say "Yes" to all the options under the NAT support
parameters, it works pretty much plug-n-play. I've tried it even behind
three cascaded NAT routers and it works.

Hello Guys,
I suspect you misunderstood.  What I am lokinng for is a hardphone that works
well.  Asterisk itself is running fine...  The issue is for example, if in
europe, behind an uncontrollable nat, are there good phones that can handle this
without requiring the configuration of the external address?

For example, both cisco and polycom, and even pingtel, require you to use an
interface method to update the external address manually...

Thanks,
Greg

Then you need to use externip= localnet=, portforward 5060 and whatever ports
you are using for RTP.  Check rtp.conf.  I don't recall if rtp.conf controls
incoming or outgoing RTP packets.  You have to portforward whatever ports the
incoming RTP is.

This has been discussed to death on the mailing lists.  Check the archives.

We did not misunderstand. I answered the question exactly as you asked it.
Someone else veered the topic away from what you intended.

They only require you to set the external interface if you are not using 
nat=yes in sip.conf.

Yes I saw you mentioned the sipura phone was good for this... I will
probably pick one up and check it out...

Thanks...  Next time I should read through the list decending rather
than ascending...
