My company has been using GTA v4 for years and only recently learned about v5. v5 has been helpful for us to connect to mobile phones but it's missing one big feature, which is being able to invite other agents to the call. We are all working remotely and sometimes it's difficult to troubleshoot problems on customer's computers by yourself. Plus we are trying to train new employees as well. So right now we are switching between v4 and v5 depending on what we need, but it would be very helpful to have all of that available in one product.
