VVX 411 Separate Number Sources

Are the VVX 411 VoIP phones able to separate number sources?  In other words, accept incoming/outgoing calls from provider A (ringcentral) and also provider B (skype for business) - 2 phone numbers from 2 separate sources.  All the information I've read defaults to having one provider issue multiple phone numbers (up to 12 separate phone numbers and users).  Other answered posts seem to indicate multiple phone sources are not possible, but sighted firmware as the reason.

Hello @OM99,

welcome to the Polycom Community.

The community's VoIP 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. The Polycom Trio has a Hybrid registration feature from UC Software 5.5.2 or later. Details can be found in the Trio Admin Guide or => here <=

Please ensure you always check the community FAQ and/or utilize the community search before posting any new topics or follow up post’s.


If you only use SIP you can have as many lines as the phones supports.

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

Best Regards
