Hello @dongyigushi ,
Welcome to the Poly Community.
Both the communities Must Read First or Read 1st and if available the FAQ reference the basic minimum information a new or follow-up post should contain.
This ensures the questions having to be asked are limited and any new or follow-up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.
Unfortunately, your post fell a bit short of the above-explained requirements and we kindly ask you, therefore, to ensure to read these sections and ensure a reply (not Edit!) provides as much detail as possible
Please ensure you familiarise yourself with the FAQs listed in my signature for your convenience.
The best and quickest way forward is to contact our Support organisation as the community is run by volunteers only.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
If official support is required please check how to phone or open a case here
The title Poly Employee & Community Manager is a community setting and does not
reflect my role. I am just a simple volunteer in the community like everybody else. All posts and words are my own & do not represent the views of Employer. ----------------
Notice: This community forum is not an official Poly support resource, thus responses from Poly employees, partners, and customers alike are best-effort in attempts to share learned knowledge.
Please also ensure you always check the VoIP , Video Endpoint , Microsoft Voice , PSTN or other FAQ's in the different sections
