When I try to make or receive calls via the wifi at my workplace, they SEEM to connect, but actually don’t. I don’t get any error message or anything. What happens is that my phone immediately shows that it has connected (even while the other party’s phone is still ringing), it stays “connected” for precisely 7 seconds, and then it drops. During that 7 seconds, if the other party picks up, no sound is heard in either direction. And regardless whether they pick up or not, it drops at 7 seconds. If I turn off wifi on the phone, calls behave normally.
I use the phone over wifi at home, and have done so at other places. It’s only an issue at my workplace. What surprises me, though, is that I never get a notification about voice calls not being available, or anything.
I’ve checked via portquiz.net, and ports 5090 & 6543 both say they are open. But I don’t know whether that check is meaningful, or what else to look for. I’d like to either fix this, or find some way to tell my phone not to even try VOIP on this particular network. I hate having to turn my wifi off every time I want to make or receive a call.
