    Now waiting for feedback from the field, which feature(s) became broken in exchange of the fixes Polycom delivered today (would be not the 1st nor the 2nd one in row to have such…)

    Hi! I am working to see if it is possible to receive multiple Lync/Skype for Business phone numbers on one Polycom phone. We got a VVX 300 due to it being 6 line and Lync compatible, not realizing that the six lines does not apply to Lync mode. Do you know if there is any way to receive multiple Skype for Business phone numbers on one phone?

      Unfortunately i’m not familiar with that option. the closes you can get is probably by using Shared Line Appearance or by creating Call Pickup Group
