[asterisk-users] Asterisk not receiving call from VPN address

[David Cunningham]

Hello,

We tried Asterisk 1.8 and 1.6, but not yet Asterisk 11. We'll keep it in
mind.

In the meantime we've decided to try a different network configuration
instead, so the VPN network is separated from what Asterisk sees.

Thanks for all the advice given.
