How do I find out who installed our routers

[leisurecentre]

I am trying to find out what IT company installed our routers as they may know more about our network and set up.  I was told that IT companies register the device with Cisco and Cisco should have the Partner IT's details?  If so who would I need to contact to find this information.  I have looked on Cisco website but cant find anything?  We are based in Queensland, Australia.

Thank you

Get all the serial numbers and enter it into the Serial Number Checker. 

Alternatively, contact the Cisco office in Brisbane and talk to one of the SE.
