Hello jcostom,
this is an interesting detail and you may want to contact me via Community mail to provide me with more details about the organisation which is running that amount of Polycom VoIP Phones that you know of.
Even that we do have 2 pages I do not have any concrete numbers of a sale that is being held up due the lack of this and therefor if you guys or our service providers do not request this (not through the community) then it will end on a list with other customer required features prior to this.
I have so far always provided our Product Management with details of each individuals post.
Best Regards
Steffen Baier
Polycom Global Services
