To clarify this, if all your sip traffic is happening over vpn's sipx won't
care to know its behind nat. Only when its behind nat and handling siptrunks
via sipxbridhe as an sbc or handling remote users via the internet (without
vpn).

If you are not using sipxbridge, server behind nat is not needed.

What kind of phone is it? Bootrom and firmware is important too.

A siptrace of that call will be helpful.

They are registered using the private address at the far end

sip:[email protected]     <sip:[email protected];x-sipX-nonat>
sip:[email protected]     <sip:[email protected];x-sipX-nonat>

They are also using a DNS locl to them (the far end router/ipsec device)

My server settings are checked "Server is behind nat" (because that's needed
because I'm behind a pfsense firewall)

What actually happens is; I call into the AA and then enters the extension,
the AA after 2 seconds say the user
I'm trying to reach is unavailable..

the weird thing is I see the phone try to dial then just stops with 1 miss
call.

Look at your registrations..

Do they show registered at the ipsec address or the public address with the
private contact address the phone is using? or are they registered at the
private address at the far end (should be).
They should also be set to use a DNS (local to them or the sipx dns server)
so they resolve it as a private address (the server is behind nat).
Can two users on the far end call each other?


I think this is possibly a case in how they route, period. If their default
route is a local gateway, the handset might be trying to contact without
regard to sipx...


outside caller--->sipx--->---vpn to remote user--->remote user

 ||
                          back out to itsp<---local gateway <--


>From the local network where the users are are you able to resolve your
sipdomain to the correct IP address? Do you possibly have "Internet calling"
enabled?

would that still be DNS?

Please ensure "Internet Calling" is disabled. The VPN phones also need to
resolve your SIP server as an internal address. What DNS are they using?

IPSec VPN and Sipx 4.2

Greetings,

I have a few sites that has an IPSec VPN setup between them. I also have a
few phones at the remote

VPN locations that registers OK and can make calls out but I cant receive a
call in. I get the message the
user is not available but the phone is register with no issues.


Heres what I have done so far.

> Disables NAT Traversal for Remote Users (dont need this since its a VPN)

> setup a phone profile for all my remote vPN phones to use the servers IP
> as the registration server
> Added all my Intranet Subnets to match my VPN Remote IP subnet


Am I missing anything?

Thanks
