I work in television broadcast and we regularly use a variety of methods for 2 way communications between sites, however these can sometimes be quite pricey and inflexible.
I was wondering if asterisk would be the right tool to achieve the following:
Raspberry Pi in site A connected to Raspberry Pi in site B over a VPN. Each pi would be connected to a USB sound card with say 4 audio inputs and outputs. I’d like to have 4, two way connections going between the Pi’s. Ideally I’d like to be able to build a nice web interface or node red style thing to establish the connections. I feel like SIP would be the most obvious way of doing this, but am fairly new to this side of the industry.
Would anyone have any pointers of suggestions on how to get started?
I’ve had asterisk up and running with webRTC clients, but want something with less of a user interface and more just straight audio links.
Thanks in advance,
