Re: Polycom IP650 - ring (external ringer) while a call is in progress?
welcome to the Polycom Community.
To my knowledge there is no way to use the speaker once the phone is in a call using the handset to sound an audible second caller via the speaker.
I would suggest you look into third party SIP solutions that offer flashing lights or similar.
