We are looking at installing a CMS and Expressway C and E for external calls.
Can anyone tell me if this solution is capable of having a Video conference call with a Microsoft teams client? has anyone tested this etc?
Cisco are not currently listed as a certified partner for Microsoft Teams - see this on the Microsoft Web Site -> Cloud Video Interop for Microsoft Teams.
The Set up Cloud Video Interop for Microsoft Teams page does mention the Cisco VCS-e though - so there is perhaps some hope that Microsoft will make MS Teams will become a little easier to work with in the future.
for my customers is also essential to be able to integrate Microsoft Teams with their Cisco infrastructures, like until now with Skype for Business.
Microsoft puts pressure on the customers to migrate from SfB to teams, so I think is very important to fill this gap as soon as possible!
