When every line is busy
Overflow and routing, so a caller in a known peak week reaches a person rather than an engaged tone.
Read about virtual systems517 has covered this part of Michigan since 1947 and nothing sits over it, so the number is barely a decision. What is genuinely different here is that the phone gets busy on a schedule other people set, and a schedule you can see coming is a problem you can actually solve.

517 is one of the original 1947 codes and covers Lansing and south central Michigan. Nothing has ever been laid over it, so seven digits still reach across town and a number printed years ago is still complete.
There is no reprinting job here and no second code to weigh up. That is not true at the other end of the state, where Detroit picked up a second code in 2025 and everything printed with seven digits stopped being complete. Worth knowing, not worth worrying about.
The code still tells a caller something, which an overlay code cannot: 517 means this part of the state. Keep one if you hold it and port it when you change provider, which is on business phone numbers. That is about the end of what the digits are worth discussing.
Most businesses experience demand as weather: it comes, you cope, you cannot predict it. A capital with a large public sector and a large university alongside it is different, because a great deal of the activity runs on published dates.
Sessions sit, budgets close, terms start and end, procurement deadlines land, and an enormous student population arrives and leaves within a fortnight twice a year. If your customers are any of those, your phone has a pattern, and that pattern is printed somewhere you can read.
That is a genuine advantage and most businesses waste it. The two failure modes are building for the peak and paying for it in the quiet months, or building for the quiet months and being unreachable in the weeks that actually matter. Both are avoidable when the dates are public.
The useful response is not more lines, which is where most businesses go first. A capital's busy weeks are not mainly higher volume, they are higher stakes: the callers are counterparts working to a date that is not moveable, and what they need is the right person rather than any person. So the thing to get right before a known peak is routing and cover. Who is named as the fallback for each person. What happens to a call when that fallback is also in a meeting. And whether anybody is watching messages during the week when a day's delay is the whole problem.
That is a rota and a set of rules rather than a purchase, which is why it tends not to get decided until the week it matters. Write it down once, before the season, and it holds for every subsequent year because the dates do not move.
There is no Michigan phone product. The software is the same one a business in Nevada is sold, it runs a long way from here, and the only thing your address decides is the three digits on the front of the number.
How it works and what it asks of your connection are on the main business VoIP guide. The rest of the state is on business VoIP in Michigan.
Three quite different economies overlap in this area: state administration and the professional services around it, automotive manufacturing and its supplier network, and the accommodation, retail and trades that serve a large transient population.
The first two want the same unglamorous things. A direct number per person, because the caller is usually a known counterpart who wants one individual and is working from a list. A greeting short enough not to punish them for calling. And something better than voicemail when that person is unavailable, because somebody working a list moves to the next item rather than waiting. Virtual phone system and auto attendant and extensions cover both.
The third wants capacity on the weeks that matter and not much the rest of the year, which is the seasonal question above rather than a feature question.
Who should not bother: one person, one phone, customers who already reach you. That is a monthly cost against a problem you do not have. And if the connection into your building is unreliable, deal with that first, because voice is less forgiving than anything else you run over a line. VoIP vs landline is the honest case for keeping copper.
None of these are about Lansing. Two of them are about handling a peak you can see coming, which is a better position than most businesses are in.

Read VoIP vs landlineProbably not first. In a capital the seasonal problem is usually not raw call volume, it is that the callers are counterparts working to a fixed date and they need one specific person. More lines do not help with that. Naming a fallback for each person, deciding what happens when the fallback is also busy, and having somebody actually watching messages during those weeks does. Sort that first and add capacity only if the volume genuinely warrants it.
Nothing has been laid over it and none has been announced. Detroit went through it in 2025, so the shape is visible: no existing number changes, but every local call needs ten digits afterwards and anything printed with seven becomes incomplete. There is no sign of that here.
Yes, and moving it is routine. A number on a VoIP service is not tied to a building, so an office move within the area does not require a new one. Port what you have rather than starting fresh, because the number is printed on things you have paid for and the porting itself is ordinary.
