Advantages of Cisco Wireless IP Phones

February 18, 2011 by Garrett Smith

Today’s empowered employees are more mobile than ever. This is a trend that is expected to continue as collaboration technologies enable experiences independent of workspace or modality.  Today’s IP phone (at least many Cisco models) provides much more than tip and ring functionality which means, only plain old voice.

If you’ve visited a local Best Buy store recently, you may have observed a retail employee using a Cisco Unified IP Phone to perform timecard functions.  Cisco phones are also used for inventory management or supply chain functions in manufacturing or other retail settings.  In healthcare, a Cisco Unified IP Phone can provide doctors with alerts on patient status and specific medical instructions.

Lastly, there’s something to be said about voice quality and service availability. In a financial services environment where decisions are made in split seconds, can enterprises afford a best-efforts, non-guaranteed service approach to voice? 

This brings me to introduce the line of Cisco Wireless IP Phones and the advantages they offer.

Let me preface this post by saying – I implore you to check with your VoIP service provider or phone administrator to ensure compatibility with your IP/PBX or service.  Most Cisco Wi-Fi phones require Cisco Call Manager License. 

Good, now that we have that out of the way we can talk about the Wireless IP Phones Cisco has to offer.
