Cisco 9861 compatible headsets

[uriarte.roberto]

We use various Plantronics and Poly headsets in our environment.  We're about 30% cisco 7965's and 70% cisco 8851's.  We are going to purchase Cisco 9861's for a new site and we're looking for compatible list of headsets for these newer phones. I'm not finding any specific information from Poly's website, I tried opening a Cisco TAC but my serial numbers for our Cisco 9861s don't work for that.

Anyone have any experience with this combination of phones and headsets?

Cisco 9861

Poly SAVI 8245

Thank YOu

Do you happen to use extension mobility a lot in your environment? If so, you might want to at least explore Cisco headsets and their built in extension mobility features, might save your users/agents some time. I've not used it yet myself but seems like a neat capability.
