Google voice and hangouts topic

OK..so my google voice messages and voice mails show up in hangouts. My partner's however do not. He is using a xperia z3 and has hangouts, hangouts dialer, and google voice all installed set up and signed in with the same gmail account. However within hangouts there are no settings for google voice. We have followed all instructions and searched google for an hour.. Tried uninstalling clearing catches and updating and even reverting to the first hangouts version that migrated in google voice all with no results.. Any suggestions?

Hangouts audio call not reliable topic

Hey guys! This is my first Android device, coming from the iOS Eco system. I am very happy with my purchase thus far! However, I'm having an unusual problem with the Hangouts audio call feature. I'm running 5.0.1 and the hangouts apps are up to date. During an audio call, I get disconnected with the person I am calling quite often, especially if I lock the screen during a call. But oddly enough it still happens if the device is awake. Is this a known glitch or is it something unique to my device? Any recommendations? I've already tried clearing the cache, but have not tried it again sense. I will also point out that calls are okay when I use the Hangouts app on the iOS devices.

Thanks for any help.

v/r,
