Both are enabled to use Microsoft Teams.
In a statement, the company said that its Poly Studio X30 and Poly Studio X50 video bars were now able to run Microsoft Teams natively.
"While the majority of office workers will start resuming their normal office routines, businesses have seen the effectiveness of remote working and there will be an uptick in remote or flex-workers where their time is split between the home and the office," said Andy Hurt, managing director, ANZ, Poly.
The Trio C60 can be used as a conference phone or else used to control other communications endpoints like the Poly Studio X Family or G7500.
It is also equipped with Poly NoiseBlockAI technology, and three microphones for 360-degree mic pick-up.
The Calisto 5300 has a dedicated Microsoft Teams button that provides instant access to the Teams application.
