Client is curennty not avaible

General Help
1

I am testing freepbx, and two clients are behind a NAT. Everything is OK, but after 10 minutes of inactivity if I call to a client I receive “The number you are trying to reach is unenviable”.

Any idea?

Client x-lite, with default config.
extensions - option qualify set to yes

Your router/PNAT box is misconfigured.

But router on Asterisk side I think?

Here is a DEBUG log - maybe it will be helpfull?

either one, the session to nnn.nnn.nnn.nnn on port 49240 no longer exists, something detroyed it, or maybe just “Polish Logic”? :wink: but one on port 49316 does.

(be careful exposing your IP’s there are bad guys out there)

The problem was that one client was running on VMWARE PLAYER so it was behind double NAT (one normal router and secon VMWARE NAT). During testing on phisical machines everything is OK.

Is it possible that (VMWARE) was the cause?
