Frequently asked questions

How many extensions can the CI11 support?

Up to 999, making it suitable for large office buildings, warehouses and hotels rather than a small setup. For a household or small business, a system with fewer maximum extensions such as the CI10 covers the need at lower cost.

Do I need a Host and an Extension, or can I buy just one?

You need at least one Host and one Extension to have a working system, sold as separate variations. Additional rooms or desks each need an Extension unit added to the same Host.

Can I use it hands-free?

Yes, it supports both hands-free and microphone-based communication, so you can choose depending on whether you need to keep hands free for other work.

How stable is the signal in a large building?

It is built for stable signal transmission across office buildings, warehouses, hotels and security stations, which are exactly the environments with the most walls, floors and interference to overcome.

What is intelligent duplex calling?

Both sides can speak and be heard simultaneously without pressing a button, similar to a phone call, which matters in a security or reception setting where quick back-and-forth communication is normal.
