Hello to all Did you ever made it to put a Cisco phone (Cisco IP phone 7940 with SIP) behind ADSL (and NAT) and make calls?? Im trying to do it, and with X-Lite I can place calls, but with the Cisco phone I cant... :(
I already putted the NAT= yes in the Cisco Phone. Is there any way of doing this ? Thanks Joao Pereira www.fccn.pt
Hi Joao,
the only way to see what's wrong is by watching the network traffic - locally and on the proxy.

Ok, Ill do some work with ethereal in the ADSL router.
But I believe the problem is, when the calls go from the internet into the ADSL router, he doesnt know to wich of the NATed IPs he should deliver the call.
The outbound calls with Cisco phone already work, it just needed to have the public IP of the ADSL router in the "NAT Adress". But... thats not a solution for ISP clients with dynamic IPs... dahm..
Why cant Cisco phones be smart as X-Lite?

Hello, Cisco doesn´t support STUN or similar like X-lite, so it is always registered, if no nathelper is used, with the private address and never reachable from the outside.
One thing you can do is to change the dsl router, there are SIP aware products on the market, i´m using for testing one Cisco1800, and have no problems with cisco phones and nat.
I think Speedtouch products are also SIP aware.

PS: I´m not realy happy with cisco phones, there are better solutions.......My opinion.

Thanks What are the "better solutions" you meant? What phones do you prefer? and what do you use to work behind NAT? Thanks Joao Pereira
