Your phones are based on an Android OS and have no heritage from the OBi ATAs and IP phones which this forum targets. As such the chances of you getting useful help here are slim.
If you think that Poly staff read posts here, there are few if any regular end-user participants who would agree. If you need convincing look near the top of the forum index page where you can read:
"News:
On Tuesday September 6th the forum will be down for maintenance from 9:30 PM to 11:59 PM PDT"
Tuesday 6 September was in 2022. More than one year ago.
