People also use SourceConnect as a way to do studio-to-studio sessions. Works very well in the studio where I set it up. Sessions to Portland, Chicago, Germany, etc all go off without a hitch. http://source-elements.com/source-connect/

You can use an ISDN bridge service to be able to talk to those studios that are still on ISDN and that works well, as well.

So, this sounds like a decent thing to also have available as a service. That way clients can be on SourceConnect pure, ISDN over a bridge, or Skype TX.

Skype is used currently sometimes if the talent is local but the producers are remote. Allows them to "be in the room". But Skype TX sounds like a decent solution for collaborating between studios.
