Is it possible for 6 phones to share 3 phone numbers?

I am in the process of configuring our small business phones.  I am currently testing a Polycom VVX 300 to see if it will meet our needs.  We would like to have 3 phone numbers be used across 6 or 7 polycom phones. I am currently testing the phone out with Microsoft Cloud PBX and logging in with my Lync account.  


The challenge I am seeing is that you can only log into one lync account per phone. Is there a different way I could architect our phone system to allow the pool of phone numbers to be shared across multiple phones?  It doesn't make much sense for us to have a dedicated phone number for each phone.

Hello TechUser,

welcome to the Polycom Community.

The community's Skype for Business FAQ contains this post here:

Jan 25, 2016 Question:How many Lines can I register using Polycom phones with Lync Server / Skype for Business server ?

Resolution: You can register only one line when Lync is set as the base profile on the phone.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Thank you for the response.  I am aware you can only log into one lync account, I did read the FAQ. My question is if there are other ways to implement polycoms in my company to take advantage of the design I would like.

Hi TechUser,


Unfortunately, you have limited options right now as Shared Line Appearance and Response Group are two features not available in Skype for Business Online - Cloud PBX (it might be in the future).

Only solution i see right now is to leverage the Team Call feature. Create 6 accounts and assign your three numbers to three of them (they will be the master account for the team) and make other users a member of these teams.

You'll need the Lync client to configure the groups though, but it should work.


Good luck!
