I need to realize a IVR with asterisk where I have only one analog line PSTN and a linux server on LAN.
I thought to use a PSTN gateway where I can put the external analog line and rotate the calls on linux server with asterisk and IVR, after I wanted come back to:
- gateway and after a single analog device;
- possible VOIP phone;
Someone can help me about the configuration?Is it correct?
Please an advice, What kind of gateway device can I buy for this configuration?
