Zaptel Hardware (1.0.2.4131) This hardware listing is partially dependent on the drivers loaded. Asterisk Zaptel Channels Those are the Zaptel channels Asterisk knows about. Things will only get here after hardware detection. # ast-cmd cmd "zap show channels" Chan Extension Context Language MusicOnHold pseudo default en 1 from-pstn en 2 from-pstn en 3 from-pstn en 4 from-zaptel en 5 from-pstn en 6 from-pstn en 7 from-pstn en 8 from-pstn en Zaptel channels Moving one layer down: the zaptel kernel drivers. Here you should see a list of them all: # cat /proc/zaptel/* Span 1: XBUS-00/XPD-00 "Xorcom XPD #00/00: FXO" (MASTER) 1 XPP_FXO/00/00/0 FXSKS (In use) 2 XPP_FXO/00/00/1 FXSKS (In use) (no pcm) 3 XPP_FXO/00/00/2 FXSKS (In use) (no pcm) 4 XPP_FXO/00/00/3 FXSKS (In use) (no pcm) 5 XPP_FXO/00/00/4 FXSKS (In use) (no pcm) 6 XPP_FXO/00/00/5 FXSKS (In use) (no pcm) 7 XPP_FXO/00/00/6 FXSKS (In use) (no pcm) 8 XPP_FXO/00/00/7 FXSKS (In use) (no pcm) Astribank Devices One level down: the Astribank drivers. First we will list the astribank devices. The '+' in the side shows the internal Astribank synchronization source. # xpp_sync Current sync: 00 Best Available Syncers: + XBUS-00 [ FXO ] (usb-0000:00:10.4-1) Next, a more verbose list, that also shows if the specific XPD is registered as a Zaptel span: # zt_registration XBUS-00 usb-0000:00:10.4-1 XBUS-00/XPD-00: on Span 1 Hardware Listing Now looking directly at the busses. You should be able to see the devices here even if their drivers are not loaded and or not available. The list of relevant devices this system seems to have: # zaptel_hardware usb:005/002 e4e4:1152 [xpp_usb] (usb-0000:00:10.4-1) XBUS-00/XPD-00: FXO Span 1 XPP-SYNC ZAPTEL-SYNC Now let's look directly at the hardware listing: USB Devices: this is the list of USB devices (such as Astribanks) on your system. # lsusb Bus 005 Device 002: ID e4e4:1152 Bus 005 Device 001: ID 0000:0000 Bus 001 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 PCI Devices: this will list PCI devices (such as Digium cards). # lspci 00:00.0 Host bridge: VIA Technologies, Inc.
