3CX vs Plivo

The main differences between 8x8, Inc. and 3CX is pricing and ease of use in my opinion. The 3CX system uses annual based pricing plans based on of simultaneous calls your company needs, not the number of extensions/users and offers a free plan. 8x8, Inc. charges per extension with different plans. We currently have 19 extensions so the 3CX system makes more sense for us, however, if your company only has a few extensions you may want to throughly consider both options. In my experience, it was difficult to add new extensions and phones with 8x8 because at least at that time we had 8x8 I could not add anything on the web admin. I had to call a sales rep which took a lot more time. Also, if you didn't purchase a phone and/or headset directly from 8x8 at a usually higher price than Amazon for example then you would have to spend anywhere from 30 minutes to hours on the phone with 8x8 tech support to program the phone to work with the 8x8 system so adding a new extension could turn into a long ordeal. I can easily add new extensions on 3CX directly in the web cpanel. Granted, if you are actually adding a new phone number you would need to purchase that number from a company like ATT first before adding it to 3CX. The difference between a phone number and an extension would be a phone number allows a customer to call in directly using that number. The extension would require the customer to call the main business number then be transferred to the extension. 3CX provides a list of supported phone models on their website
