FINDING PUBLIC ISDN SITES

When you need to find a ZephyrExpress, Zephyr, or compatible codec to connect with in

another city, there are a number of resources to which you can turn. There are many

hundreds of sites around the country – and the world – which offer a wide variety of

services.

Some are music recording studios; some are broadcast stations; some are recording stu-

dios specializing in broadcast projects; and many are home studios belonging to an-

nouncers or producers. Some come with award-winning engineering or vocal talent,

while others are offered “bare.” Chances are, you’ll find what you are looking for

somewhere below...
