You can see PRI debug info on the console. Extremely valuable in troubleshooting. http://www.voip-info.org/wiki/view/Asterisk+CLI Zap channel commands zap destroy channel: Destroy a channel zap show channels: Show active zapata channels zap show channel: Show information on a channel zap show status: lists all the Zaptel spans. A span will apear here whether or not its channels are configured with chan_zap. zap show cadences: Show the configured ring cadences (available e.g with Zap/1r2). zap set swgain(<= 1.6): set the (software) gain for a hannel. Temporary equivalents of rxgain and txgain in zapata.conf. zap set hwgain(<=1.6): set the hardware gain for channels that support it. zap set dnd(<=1.6) set a channel's do-not-disturb mode on or off. The following commands are available if the channel is built with support for libpri: pri debug span: Enables PRI debugging on a span pri intense debug span: Enables REALLY INTENSE PRI debugging pri no debug span: Disables PRI debugging on a span pri show spans: List spans and their status. pri show span: Information about a span. pri show debug: show where debug is enabled.
