Hi Forum,

I am using a cisco 2811, with T1 card trunk to a legacy PABX, I need to monitor the no. of calls on the trunk.

I do not have a call manager, how do I monitor it over a period of time?

Thanks much,

I am not sure but you may set up the router to logging the T1 activity on a syslog server.

There is also the show call history voice brief that saves some information for a period of time.

Thanks everyone for the help. I guess I will have to manually collect the data.

Thanks much,
