Hi, core show function CHANNEL mentions "Additional items may be available from the channel driver providing the channel; see its documentation for details". Where can you find DAHDI-related info ? More specifically I would to know within dialplan, which Dahdi (trunk) group current dahdi channel belongs to (a bit like command "dahdi show channels group 1").. How can I find this ? (precisely, suppose Dahdi spans 1 and 2 belongs to group 1, spans 3 to group 2. Which dialplan function would output 1 or 2 depending on the channel id calling this function ?)
