Liveware requires 16 or 24-bit colour. DCS called too early. The local camera may be checked by clicking the local video icon. A local loopback test may be selected from the Diagnostics menu, which will also test the sound. One of these numbers should be used to perform a remote loopback test in the diagnostic window, or just dialled from the phonebook.
Some numbers are available with training videos or promotional material.
It is possible to call a regular phone by selecting Audio Only . The same audio processing and echo cancellation is done, giving the 1-second delay as in a video call. The ISDN line comprises two B channels of 64kbps each, and a D channel which is normally used for signalling. Some phone lines and equipment cannot support the D channel, so borrow bandwidth from the B channels leaving 56k. Conversely, some equipment cannot support 56k working.
