I'm trying to run Jitsi from home to connect to an Asterisk system at
my office and not able to successfully make any calls unless I use
VPN. It will REGISTER fine and the OPTIONS requests are handled, but
not INVITE. Wireshark shows it going out, but tcpdump on the Asterisk
end shows it not being received and the call stays in "initiating" status.
Obviously, the routers are the first things to suspect, but I have a
SIP phone (an Aastra 6757i) on the same router as the laptop running
Jitsi and the phone can make calls just fine. So I'm at somewhat of a
loss to understand what's different here with Jitsi. Any suggestions
as to where the next place to look is?
