Can we use one phone number across multiple phones?

[JohnDoe]

Is there a way to assign the same public number to multiple phones or do we need to get a public number per phone?

The phones do have the ability to apply multiple numbers to one device.  I don't see why this wouldn't work with overlapping numbers.  Ideally for Customer Access Rep stations you would want calls to ring on all lines so I believe this is an available feature.

To assign multiple phone numbers to a phone, perform the following steps:
1.Log in to dashboard and browse to Phones > Monitor > Phones.
2.Click on the phone you want to assign a number to.
3.Click the pencil icon next to Public Number.
4.Click the down arrow next to Public Number.
5.Select a phone number from the numbers you have previously purchased from your provider. For more information on how to purchase more numbers, click here.
6.To add another number to the phone, click the down arrow next to Public Number again.
7.Select another phone number from the list.

This does not work the way you explained . Once a number has been assinged to a phone, you can not select that number on another phone. 

You would need to create a "Call Group", then assign the Number to the Group, then assign Phones into that group via a "Tag".

There's a tiny bit of mis-interpretation by @MerakiJockey505 regarding the original question, which is: one (1) phone number to multiple phones. What @MerakiJockey505 described was the ability to assign multiple phone numbers to one (1) phone - and that is in fact, a supported feature as documented in this following Knowledge Base article: https://documentation.meraki.com/MC/MC_Network_Administrator_Guides/Directory_Management/Adding_Mult...

To answer the original question, the answer/solution is yes - by deploying/configuring Call Groups as @Welles correctly identified and recommended.
