Product Information

iPhone Headset Adapter transforms a typical iPhone or Smartphone headset into a Cisco 7940 compatible headset.  This headset adapter converts the audio headset with single TRRS 3.5mm audio plug into the RJ-9 modular plug that connects to the Cisco 7940 IP Phone.

This solution offers you great flexibility to choose a headset you like. For instance, you will be able to use your existing iPhone headset that you may already have. Or purchase comfortable computer headset with iPhone-style plug. You may choose between behind-the-neck and boom-style headset. And you still can use the same headset with your smartphone.

Our headset adapters allow you to use full functionality that Cisco 7940 Unified IP Phone provides. You can answer a call with either headset or handset, and you may switch between them during the conversation. You can use Auto-Answer with the headset or the handset. You can save volume settings separately for speakerphone, handset or headset. These adapters are compatible with hearing-aid in-line amplifiers.
