I need to create a sandbox environment I can work in that behaves like an actual connected environment.
I can set up two voip phones, each one on a separate LAN, load vitalpbx on a third (cloud emulation) LAN, connect all three with routers, and put a DNS server in the “cloud” LAN.
Now the phones can talk to the vitalpbx server, and believe they are on the real Internet.
What I need to make happen is to open a web page on an incoming call, transfer it to an IVR, and then have the call return to the extension that first received it.
Ordinarily you need a VoIP SIP service to provide DID trunks in order for things to work in the real world.
What I saw is that SIPp provides the VoIP SIP emulation, which I would expect should also run in the “cloud” LAN.
Am I missing any elements needed to make this work ?
