debug detail logs from 2801 router

i have done the following:

access-list 169 permit ip host <vpn client ip address after connecting through the vpn client> host <ip phone ip address>

access-list 169 permit ip host <ip phone ip address> host <vpn client ip address after connecting through the vpn client>

After creating that type the following command:

debug ip packet 169 detail

After that try to make a call through your ip communicator and see the logs on the router

My question is this, how do I retrieve the detail logs?

That debug will send its output to syslog with severity level of 7. There are several ways to see the log output:

- if you do terminal monitor a copy of the log messages including the debug output will be sent to your telnet/SSH session at the time that the output is generated.

- if you have enabled logging buffered at level 7 (which is the default) then copies of the debug output are written to the logging buffer. You can see the output using the command show log. Note that the logging buffer is a circular buffer, the debug output is written to the buffer and remains available in the buffer until the buffer gets full and then the debug messages are overwritten.

- if you have enabled logging to the console at level 7 then copies of the debug output are written to the console at the time that the output is generated by debug.

To stop generating the logging output you turn off debug using the command no debug ip packet 169 detail. Or you cn use the command undebug all.
