[cisco-voip] Monitor debug isdn q931 on multiple gateways?

[Dane]

Is there a good way or tool that can be used to monitor q931 on
multiple devices at one time?

Example, last night I had a issue where we were trying to determine if
a number was hitting one phone system or another.  Due to the area
code of the number I got into the gateway that had PRI's in that area
code and did a debug isdn q931 to confirm if the number was hitting
that system.

Well nada.  So I assumed it wasn't.

However that number actually had a remote call forward set at telco
side pointing to a number on a different gateway but same phone
system.  I am not aware of a good way to monitor a LOT of gateways for
the q931 info at one time.

But after the issue last night it made me wish there was some way to
aggregate a bunch of debug isdn q931 output from multiple devices in
near real time and be able to search within all that data.

Any one familiar with something that might do this that I am overlooking?
