Not uncommon. At Boston's WBZ, the main call-in number was originally ALgonquin 4-5678 (617-254-5678), which still works but has been superseded by 254-1030 to reinforce the branding. But the contest line is in what was the Boston "choke" exchange, 617-931-1030. The main switchboard number is 617-787-7000, which would have been STadium
7-7000 in 2L+5D days, but I don't know if that number was in use back then. Those three exchanges historically belonged to three separate COs: 617-254 is Allston, 617-787 is Brighton (both now in the same ratecenter IIRC), and 617-931 is a downtown Boston exchange which I think was historically located at the NET&T headquarters. WBZ-TV (channel 4) used to have 617-782-4444, but I doubt that is as old as the number would imply. (WBZ-TV has been at the same location since
1948, when that number would have been STAdium 4444.)
