I can not for life of me figure out why these two debugs will not show the actual calls coming in/out of the router. I have term mon on, I see events, but no call traffic

Hello.


It is not a rumor. If you use telnet, you must to use the terminal monitor command to see the debug. This must be done for all debugs from telnet


Hope this helps, please rate post if it does!

Are you sure is an isdn?


If its a T1 CAS you might want to try 'debug vpm signal' 'debug voice ccapi inout'


What is your topology?

nope just 2 pris in a 2811 with MGCP. I typically just run these debugs to make sure the call is actually hitting the VG outbound and inbound and I can also see what digits are being sent from the carrier. Im getting nothing!@ it's really odd

You can see the output from any of the logging methods, IF you set that method to level 7 (debug)


Try:

"logging console 7"

"logging terminal 7"

or

"logging trap 7"


depending on whether you want to see debug output on the console, telnet, or syslog.

I believe the default for console is 5(notification). Just "show logging" to see the various levels.
