What does this mean? You no longer need an on-premises PBX (with the option of a local gateway), so the install, commission and operation of your telephony is a whole lot simpler. ![Cisco Webex Calling](https://blog.iptel.com.au/hs-fs/hubfs/Blogs/Cisco%20Webex%20Calling/Cisco%20Webex%20Calling-still.jpg?width=1475&height=790&name=Cisco%20Webex%20Calling-still.jpg)   --- ## Cisco Webex Calling Before we deep dive into what Webex Calling is, as a solution, we need to answer the big question: - ***Why should we consider moving IP Telephony to cloud?*** Is it *worthwhile* to migrate an Enterprise Telephony system to the cloud? To answer this question simply, we need to understand what cloud is and what benefits it offers. Let's start at the beginning... Related reading - [Cisco Webex Calling](https://iptel.com.au/services/cisco-webex-calling) --- ## Cloud Computing and Telephony If I were to put this in simple words, cloud computing is a neat way to rent IT instead of buying it. An easy example would be renting a car instead of spending say $30,000 to own and maintain it. Here is a list of some other benefits of the Cloud: - Cost-effective - Availability of resources - Scalability on-demand - Ease of use - Timeliness - Reliability with respect to redundancy The above-mentioned are just some of many benefits that companies can take into consideration when opting in to migrate to the cloud. With the ever-increasing demands, it only makes sense for companies’ approach to enterprise telephony to go cloud to reap these rewards. As a result, we need to explore a well-known and best in market vendor who can offer us the answer. I would like to introduce you to the Webex Calling solution by Cisco Systems.

[![Webex Calling Overview](https://blog.iptel.com.au/hs-fs/hubfs/Blogs/Cisco%20Webex%20Calling/Webex%20Calling%20Overview.png?width=322&height=327&name=Webex%20Calling%20Overview.png)](https://help.webex.com/en-US/article/0xvuwab/Overview-of-Webex-Calling)The image on the left explains this quite well. As you can see you have your Webex client (or indeed any compatible Cisco IP Phone endpoints), which can communicate over the cloud and register with Webex Calling - no local PBX. Some customers do want the security of a local gateway of course - so there's the option to include that, if you wanted to have local PSTN access. Webex Calling allows for a mix and match of the best of cloud, utilising your existing phones and having the option of local breakout, if you need it.   Related reading - [Overview of Webex Calling](https://help.webex.com/en-US/article/0xvuwab/Overview-of-Webex-Calling) --- ## What is Cisco Webex Calling? Webex Calling is a **complete enterprise-grade cloud calling and team collaboration solution** offered through a flexible subscription model.

No matter where you are working, you can rely on Webex to call and connect from anywhere, on any device, whether it is on your computer or mobile devices. Cisco is now offering cloud calling with complete PSTN coverage.  Hybrid work has changed the nature of work. Both employees and employers need to re-evaluate the way they conduct business. This is vital to accommodate the way we interact with customers and work colleagues alike. There now exists the need for a hybrid workforce environment where companies can complement remote working (WFH) as well as to complement working from office, as the ***new normal*** of future work strategy.

Cisco Webex Calling is a cloud phone system. It replaces an on-premises PBX with calling delivered from the Webex cloud, used through desk phones, the Webex app and mobile devices. ### Can I Keep My Existing Phone Numbers? Usually, yes. Existing Australian numbers can normally be ported to the new calling service, and the move can be planned in stages to avoid disruption. ### Does Webex Calling Work With Microsoft Teams? Yes. Webex Calling can integrate with Microsoft Teams so users can make and receive calls on their business number from within Teams. ### What Do I Need to Move to Webex Calling? A reliable network and internet connection, compatible phones or the Webex app, and a plan for number porting, call flows and emergency calling. A short assessment covers all of these. --- ## Cisco Webex Calling: Summary I hope this has been a good and educational read. Like many sectors of networking, IP Telephony is the latest to go cloud.  The ability to use your existing Cisco handsets, while making use of the Cloud telephony PBX makes this a pretty compelling offering. Agile. Ease of Use. Simplicity. Three words which summarise the offering pretty well.
