[GreenKeys] Are there any telephone switchers in the group?

[David S]

Not CO, but I did work on Nortel Option 11/61 PBXes.  There is a huge 
drive to move everything to IP telephony (local and infrastructure) but 
one thing the COs did have was incredible reliability that the IP 
networks just cant match, at least the COs in my area.  There is 
evidence of the Telco's rigorous maintenance routine in the form of 
maintenance logs at my larger facilities that have the last entries in 
the early 2000s.
