[Asterisk-Users] "detected NAT type is full cone" for BT behind nat ?

[Robert Rozman]

Hi,

I wonder what does this warning 399 mean and how to workaround?  "sip show
peers" says that sip client is unreachable althought it works with some
eexceptions ...

I saw posts in this list about setting codec to ilbc, is this right action ?

Also, I'm very interested if anyone succeded on Asterisk behind one firewall
and Grandstream behing another ?
I' almost got it working (if calls from BT work, problem is when call is
coming to BT as local extension)...


Thanks in advance,

regards,

Rob.
