WebRTC Headset call control for NICE CXone

We are using NICE CXone with a WebRTC interface. We are looking for some help on audio challenges with our Poly headsets. Few examples are  Agent not being heard by customer Customer not being heard by Agent NICE CXone MAX Agent Desktop not being able to open agent leg due to unavailability of audio device Sudden silences for 2/3 seconds Agent Audio randomly stopping to work / reach customer Customer Audio randomly stopping to work / reach agent  Headset devices we are using :  SAVI 8220 Also tried wired model : Blackwire 5220 Now I am thinking to implement a call control solution using custom url, see solution below (via url) from Jabra.  So thinking if Poly also has similar solution available.  (https://developer.jabra.com/site/global/software/nice-cxone-max/docs-1-0.gsp)
