Comrex is the de-facto unit in radio. Their boxes start at $1400 US 
and go up to about $5000. They're gear is not much more than a 
dedicated small Linux box with a bunch of Codecs in it, and audio 
converters for input and output. They work incredibly solid over 
normal cable Internet to connect a remote host to a radio network 
(which in turn sends it to a satellite, which is received by stations 
that rebroadcast it). They're also used for connecting from radio 
studios to the transmitter, which is often at a different location, 
up on a hill somewhere.

That company also makes similar gear for television.

There are competitors that make boxes that cost less, but don't do as 
good of a job. If someone were to make a cheaper box that did the 
same thing, did it as well, and marketed it correctly, they'd be 
incredibly rich.

I have 12 rotating co-hosts, all in different towns from me. I can't 
afford to buy them all Comrex boxes, so have been connecting to them 
via Skype. (And I connect to the Network via my Comrex Bric-Link 
unit.) Tomorrow I'll try Opus on Blink to connect to a few of them as 
a test. But the issue is this: My show is a live 6 days a week, I'd 
like to be able to take a day off once in a while. I could if two of 
my co-hosts (without me and my Comrex) can use Blink to connect to 
the network's Comrex and do a show without me. They can via G.722, 
but it doesn't sound great. I guess I'll have to hope Comrex adds 
Opus support soon. They said back in January they have plans to, but 
haven't yet.
