Normally 3CX is used for enterprise telephony, but for some parts of that, we use separate solutions. We use it along with Zendesk, which is a cloud-based CRM. There are some integrated aspects of it we are also using. We are primarily on Zoom. We do conferences sometimes on 3CX but not often. For enterprise, we have Zoom We started using Zoom much earlier than 3CX, so we continued with that. People are pretty comfortable with Zoom. We have four implementations of 3CX. One has around 200 to 300 extensions running on it. There's one with 700 and another one that is not really in use yet.
