Hi,

I know this is slightly off topic but I figured the knowlege here is probably
the best on the subject..

I want to setup remote offices with 4 to 6 SIP phones (SNOM 200) using ADSL and
the internet to connect to the Asterisk box..

These phone will be behind an ADSL router using NAT...

I don't want to setup another Asterisk system in each office so IAX is not
an option..

I could use static port mapping on the NAT gateway but I am not sure how to do
this for 6 phones.. I guess I would have to allocate a seperate port to each..
Also this could have major security implications..

I could use a STUN server but I have not found a free one yet..

I could use an ADSL router with a built in SIP proxy/registrar but the only one
I have found is the Intertex IX66 and they seem quite expensive..

Anyone got any ideas or thoughts?? or even better experiences..

Though it does not provide a solution to your challenge with the
hardware you mention, I have had very good luck with Cisco ATA-186
devices (one or many) behind NAT (nothing special... any basic NAT
router seems to be fine) connecting via SIP to an asterisk server with a
public IP. My understanding is that some of the IP phones from Cisco can
do this just as well, if you want to avoid having ordainary phones on
the desks.

     I overcome the ordainary-phone problem by putting Nortel Vista 350s
on the ATA-186s... They don't deliver the features of the true
IP-Phones, but my users seem to expect that an IP-connected telephone
look like something out-of-the-ordainary. :)

Just my $0.02...

Hello,

a. the snom200 should have UPnP implemented - hence a UPnP-enabled gateway
should help it.

b. Alternatively, only 5 clients (without license upgrade) can be supported
by the Intertex66 - which only costs around 250 USD.

oh, but does adsi work over the ata186 
-can add you own softkeys by editing the asterisk.adis config file
-run Comedian voicemail
-run the getcpeid
etc

There is a free STUN server at http://www.vovida.org/. I haven't tried
it yet, but from what I hear, it seems to be an okay product.  They have
Cisco's backing too from what I see on their website.

For me an upnp gateway works just fine. I'm using a linux box with the upnp
lib and linux-igd installed.
