To simply state that the Cisco endpoint portfolio is extensive and diverse is an immense understatement. The portfolio has evolved greatly since the first Cisco IP Phones were made available after the Cisco acquisition of Selsius in 1998. At that time, the true advance in technology was the fact that the phone was an Ethernet-connected device running a TCP/IP stack and capable of providing basic telephony features.


The SEP stands for Selsius Ethernet Phone. Cisco has slowly started to move away from differentiating IP Phones, software-based clients, desktop video endpoints, and immersive TelePresence room-based video endpoints. In the past, the distinction was important. Now the lines are blurring. These endpoints all have similar characteristics at the most basic levels and can be managed in a nearly identical manner.


It seems that video has become an increasingly vital means of communication. This means that video capabilities must move from that one conference room or the executive board rooms into the masses.


Every device must allow people to communicate in the manner of their own choosing. So, IP Phones, whether video capable or not, are simply collaboration endpoints.


Whether the device in question is an IP Phone, software client, desktop video endpoint, or an immersive video endpoint in a conference room, it is simply a collaboration endpoint.  Making a video call is now easier than making a traditional voice-only call.





The Cisco IP Phone portfolio consists of a rather wide array of options and feature sets. This diversity of features allows flexibility in deployment based on the needs of the individuals using the phone and the phone’s general purpose (lobby phone, break room phone, conference room phone, and so on).


There is no one-size-fits-all mindset when it comes to collaboration technologies. Different users will have different needs/desires in how and where they choose to communicate. The focus rests squarely on creating the best user experience regardless of the devices in question.


This section covers the following Cisco IP Phone models:

3900 series

7800 series

7900 series

8800 series

8900 series

9900 series


The order of is merely based on numeric value of the series rather than form, functions, or features.
