Hi Group,
What is the purpose of SIP protocol support located at
Network Protection --> Voip --> SIP
Is this a feature that you enable in order to deal with RTP on high port numbers without having to open a large range of ports?
I'm using an asterisk based pbx that is sitting behind an astaro firewall. It is natted with sip port 5060 open to it only.
A quick check of the firewall logs seems to indicate the high ports are being blocked.
PS - we will have some voip phones out on the Internet needing to connect to the pbx sitting behind the astaro without vpn.
