[asterisk-users] NAT issue (i think?)

[Ron]

Hi Danny

On the pap2 by default it is set to 3600 and i have not change that.
by the way, is the NAT keep-alive same with the NOTIFY message? coz i am 
seeing my asterisk respond to those as bad event could that be causing 
it to loose the registration?

here's the registration from ngrep:
