Nope, it’s acoustic phone program 
but there is a lot of background noise since the volume is set much higher.
Ask your fitter to adjust that program, to put heavy noise cancelling and other adjustments, then try.
You should recognize it immediately when you hear the ringtone.
Unfortunately, marvels and paradises don’t automatically switch to tcoil program, if that’s what you meant.
There should be no ambient noise over the telecoil. For example, if you touch the microphones.
What you do have is insane amount of static noise (depends maybe on your loss, so which frequencies are higher), to the point that I cannot use it to really comprehend someone unless I’m in really quiet.
Like, I’ve tried in bus, using tcoil option on aids with neckloop and screetching from powerlines I guess was unbearable and loud to the point that I really didn’t understand my mother on the phone. I did use public tcoil program though, not phone tcoil, maybe phone one would behave differently? I might try one day.
Your mileage may vary, so test and see for yourself how it works.
Also, is there a way to see how much battery life is left for the size 312 and 13 battery versions in the Phonak app? I know it shows the battery life for the Rechargeables under Remote Control but I haven’t been able to find it for my 312 batteries. Thanks!
No, it’s only for R version.
