On Yealink's you can have a BLF key.
Use the Intercom Feature Code *0 (Kazoo Part) + BLF Button of user/device you want to call.
This will allow for the two way call.
That 'might' be an option? But I don't know polycom's.

That's a regular Kazoo intercom call which goes over SIP. Jack is referring to multicast paging which is directly phone-to-phone.
Edit: I didn't see your first part lol...but yeah, you can do that on Polycoms too.
