Fred wants to know if he can tell that a phone call is being forwarded to another number. Leo says not anymore. In the old days with physical switches, users could. But it's all digital now and automatic. In fact, most of it is done in software, so it's completely opaque to the caller. In fact, it's likely not done at the phone company level, but at a gateway to a VOIP network using something like Ring Central.
Eddy just wants to listen to music or stream on his phone without being disturbed. How can he turn off his phone without losing internet? Leo says that he can maybe turn it off in phone settings. He could turn on call forwarding. *72. Input another number, and it will forward all calls to that number, like a landline or a Google Voice. Then *73 to turn it off. He can also try turning on airplane mode, and then re-enable WiFi for data only.
Phil is having issues with Google Voice, missing text messages, and voicemails. Leo says that Google has let Voice fall in quality since it bought it and may be moving away from it as a viable service. Even Hangouts isn't what it used to be. Leo used it when it was originally called Grand Central and it was great. But over the last year or so, it's really gotten hit or miss. Nowadays, Leo just uses it as a call forwarding service. But it may not be Google's fault. It may also be phone carriers who are engaging in anti-competitive behavior.
