It routes call audio through the wireless headset system and allows supported incoming calls to be answered from the headset’s call-control button. This is a legacy accessory intended for older iPhones equipped with a built-in 3.5 mm headset socket.\u003c\/p\u003e\n\n\u003ch3\u003eUse a CS500 Headset with a Compatible iPhone\u003c\/h3\u003e\n\n\u003cp\u003eThe API-28 connects the 3.5 mm headset socket on a supported iPhone to the base of a compatible CS500 wireless headset system. This allows the mobile phone’s call audio to be handled through the wireless headset rather than through the phone itself.\u003c\/p\u003e\n\n\u003ch3\u003eRemote Mobile Call Answering\u003c\/h3\u003e\n\n\u003cp\u003eWhen the API-28 is correctly connected and the headset base is configured, an incoming mobile call can be answered using the call-control button on the CS500 headset. This helps users respond without needing to handle the connected iPhone directly.\u003c\/p\u003e\n\n\u003ch3\u003eDesigned for CS500 and CS500 XD Systems\u003c\/h3\u003e\n\n\u003cp\u003eManufacturer compatibility guidance identifies the CS500 and CS500 XD Series as the supported wireless headset platforms. Documented CS500 examples include the CS510, CS520, CS530 and CS540, but the exact headset model should still be checked before purchase.\u003c\/p\u003e\n\n\u003ch3\u003eDirect 3.5 mm Connection\u003c\/h3\u003e\n\n\u003cp\u003eThe cable requires an Apple iPhone with a built-in 3.5 mm headset socket. It is not a Lightning or USB-C accessory, and operation through a separate port adapter has not been confirmed by the manufacturer documentation used for this listing.\u003c\/p\u003e\n\n\u003ch3\u003eOptional Online Indicator Support\u003c\/h3\u003e\n\n\u003cp\u003eThe API-28 is described as compatible with selected Plantronics Online Indicator or busy-light accessories.

Compatibility should not be assumed for other iPhone generations simply because they use an Apple operating system or can accept a third-party audio adapter.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features:\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eConnects selected Apple iPhones to compatible CS500 wireless headset systems.\u003c\/li\u003e\n\t\u003cli\u003eUses the iPhone’s built-in 3.5 mm headset socket.\u003c\/li\u003e\n\t\u003cli\u003eAllows supported incoming mobile calls to be answered from the headset.\u003c\/li\u003e\n\t\u003cli\u003eDesigned for Poly\/Plantronics CS500 and CS500 XD Series base stations.\u003c\/li\u003e\n\t\u003cli\u003eSupports compatible optional Plantronics Online Indicator accessories.\u003c\/li\u003e\n\t\u003cli\u003eProvides a wired interface between the mobile phone and wireless headset base.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility Information:\u003c\/h3\u003e\n\n\u003ctable\u003e\n\t\u003cthead\u003e\n\t\t\u003ctr bgcolor=\"#444444\"\u003e\n\t\t\t\u003cth style=\"color: #ffffff;
