New Feature: For group calls, allow a host to invite other participants. If a caller drops off for wifi (or other), they can dial in.
Today's Limitation: when a group call is initiated, and someone falls off, the flow of the call is greatly interrupted b/c it requires voice command or going through screens to get them back. Its essentially, non workable if this is something you do often.

Portal has revolutionized communications between remote employees in our company, and those in the headquarters. Its completely changed the interpersonal dynamic in a positive way that no other hardware or software can. As remote or 'work from anywhere' becomes the new norm, this solves for the interpersonal elements that are key components of office relations. In fact, now all the employees in our headquarters, have one on their desks, in addition to our remote team, and communicate with others in our own office vs. calling an extension. We are a financial service company, and are going to be using them to ship out to clients who need service or support; they can portal our teams.
Basically, the only real limitation is when we want to get teams together in a group. Either phone (thumbs down), or zoom, where you can host a call, are the only options. Those technologies had their time and have done zero to change interpersonal dynamics and collaboration in the work force, and with this one tweak, portal can disrupt their entire business, and put real horsepower behind the work from anywhere movement.
