Interop (interoperability) enables you to test between your and DIDX networks before activating business with DIDxchange. See how DIDX works now; we offer every DIDX member 2 free DID numbers, one UK DID and one USA DID. These DIDs test successfully. They are pointed at 18005558355@tf.voipmich.com that plays an IVR when called. Check the numbers by calling them to see they are alive and reachable from your telephone. Browse a copy of the DIDX member manual in your favorite format at http://www.didx.net/manual and see DIDX demo videos at http://www.didx.net/videos. Requirements: 1.
