SoundStation VTX 1000 Does Not Ring
When the software download starts, note the connect rate that is displayed as the connection is established. You may cancel the software download once the connect rate has been displayed.
If the software download connect rate is below 19.2 kbps, the line will not support wideband calls.
No Caller ID
Call Waiting: Call Waiting signals will interfere with wideband operation. It is highly recommended that Call Waiting be disabled by the phone company (or PBX administrator) for lines used for VTX 1000 wideband calls.

Cannot Connect In Wideband Mode
Operation Manual
You must be connected to another SoundStation VTX 1000 to enter wideband mode.
Modem Train Time: The short train mode (6 seconds) should only be used on high quality phone lines. If you consistently have problems achieving wideband mode, set the modem train time to long (12 seconds). Refer to page 36.
Bridged Calls: Wideband mode currently does not work with external conference bridges (i.e. multiple calls).
Line Quality: The VTX 1000’s modem operates in two modes, wideband voice mode and software download mode. In software download mode, the modem connects at higher rates, typically those rates achieved with a data modem on the same lines. However, in wideband mode, the connection rate is optimized
Poor line quality can prevent connections in wideband mode. The VTX 1000 will connect in wideband mode on connections as low as 12 kbps. However, if the line quality does not consistently support 12 kbps, the unit will connect in narrowband mode. This will be the case if your local loop is longer that 12,000 feet. Also, this can be the case with shorter loops if there is a problem on the line. Please contact your local phone company for resolution. In general, a typical data modem should be able to achieve 24 kbps connections in order to support a VTX call.
In order to test your line quality, perform the following test: Configure a VTX 1000 which has a good line as a software download server in accordance with instructions on page 44. Configure the unit with the line problems to receive a software download from the
