Is there any published studies on the number of incoming calls that are placed to a US Wireless mobile number that fail to actually reach or ring the phone? Any studies that go through the most common reasons why that occurs? I am curious about network prioritization, cell tower capacity rules/management, and why, if a cellular device has a "good enough" connection to a tower might the signal to the device that there is an incoming call NOT be sent? I have a lot of customers who get frustrated when there is a call we are forwarding or making to them, and we reach their mobile carrier, but their mobile device does not ring. They say "I'm looking right at it, and you say you're calling it, but it isn't ringing!" As if the wireless network is somehow under our control. There's a lot of marketing about "network quality" and "network coverage" but very little about dropped calls, or calls that fail to start and go straight to Voicemail.
