Hello,
i try to connect my SIP Client (linphone) via VPN to FreePBX.
The routing looks OK. I can ping the Endpoints and traffic is routing.
I can also Register my Sip Client.
debpbx*CLI> pjsip list contacts
Contact: <Aor/ContactUri..............................> <Hash....>
<Status> <RTT(ms)..>

Contact: 731/sip:731@192.168.30.132:5060 163a967d99

Contact: 734/sip:734@10.8.0.143:5060 1b1aa8cbac

So far so good. When I try to an other extension I get a timeout.
tcpdump:

I think the SIP/2.0 401 Unauthorized is the problem.
I also had add the VPN IP range to the local_net but that does not solve
the problem.
root@debpbx:/etc/asterisk# grep -ri 10.8.0
sip_general_additional.conf:localnet=10.8.0.0/24
pjsip.transports.conf:local_net=10.8.0.0/24
