A Communicator call placed to an RCC-enabled contact rings all of that contact’s Communicator-enabled devices, but the phone that is integrated with the PBX system will not ring.
Klic iz Communicatorja do stika, ki ima omogočeno daljinsko upravljanje klicev, zvoni na vseh napravah tega stika, kjer je omogočen Communicator, telefon, ki je povezan s sistemom PBX, pa ne bo zvonil.
