On my DAHDI port, and not on my SIP service, the caller and a 500 set on the line experience as many as 5 rings before the dashboard graph responds and inbound ring group rings.
And, what is the best way to live monitor a call’s progress? Please suggest possibilities. Thank you.
I don’t use DAHDi so I’m not sure what the debug commands would be for DAHDi specially. However, verbose output of the call showing how it is processing through Asterisk may point to something.
