VoiceTronix OpenLine and OpenSwitch Cards

The VoiceTronix OpenLine and OpenSwitch Cards are an inexpensive line of FXO and FXS cards for standard analog lines. In low density implmentations they can be a highly effective solution. The OpenLine 4 has 4 FXO ports, the OpenSwitch 6 has 6 user-configurable ports that can either be FXO or FXS, and the OpenSwitch 12 has 12 user-configurable ports that can either be FXO or FXS.

The VoiceTronix hardware is supported by the chan_vpb channel driver in Asterisk. The driver is part of the standard Asterisk source distribution and is compiled as part of the standard build. The ring type code can be modified to specifically support either US (United States) or AU (Australia) ring tones. With the improvements in indications.conf this will be depreciated.

The chan_vpb channel driver is loaded by the use of the vpb directives in either the extensions.conf or somewhere that the channel is used. To configure a specific card, you edit the vpb.conf as per that section of the documentation. The VoiceTronix hardware needs a kernel module to operate, vpb, and that must be acquired from VoiceTronix:
