Cisco™ 8851 desk phone
The devices' availability depends on your solution
Desk phones, conference phones and a range of hardware products are available in One Net Business and One Net Office.
What is the Cisco 8851 desk phone?
The Cisco 8851 is a full-featured VoIP (Voice over Internet Protocol) phone that provides voice communication over an IP network.
How do I use a Cisco desk phone?
You use a Cisco desk phone as you would any other desk phone. You make and receive calls in the same way you are used to, but the call connects over the internet instead of a phone line.
Your desk phone interacts with One Net
There are several features of your Cisco desk phone that interact directly with One Net.
- You can use phone shortcuts to do tasks, such as activating and deactivating call forwarding.
- Some buttons on your phone interact with specific One Net services. For example, if you have a Busy Lamp Field (BLF) key set up for a contact, you can see that contact's availability to take calls.
- Your desk phone has direct access to your organisation's One Net Address Book, so you always see the latest information.
