I spoke to my friend at EE who works in the network planning and integration team on Friday about wifi calling to see if any update.
He said that the service is on a friends & family along with closed user group trial, which has identified some issues in particular with two home broadband providers.
This is proving quite difficult to overcome as the issues lay with the broadband providers in how they have their network configured and another how they set their hubs/routers up. The providers do not seem to be in any rush to fix and patch this. Possibly due to thm being landline providers as well so maybe worried about falling home calls made.
As has been stated before this needs to work seamless with customers having to start tweaking and amending home broadband setups just to get wifi calling.
Meanwhile there is another team travelling out and about testing this on public wifi hotspots, on trains,underground and also they have started visiting some large EE corporate customers to test on their networks with one even setting up a new wireless AP just for staff to use for wifi calling as over 1200 staff in the office. Although are probably very confused why a new wireless network has appeared called EE wifi
He is not sure how much staff training has taken place on wifi calling he thought it was just a handful of managers and team leaders that had been trained,but comments on here may indicate that all staff have started having training this week hence the advisor thinking it was live now.
