I just started seeing the same issue.
same problem here
I'm having the same issue however I can't hear them and they can't hear me. I'm using Apple 6S and Mac, both are having the same issue and its starting to be a real problem! Is this a bug with the apps, how can I fix this?
Same issue since last update, ticket submitted. Rebooted, re-installed dialpad, used both internal mic/speakers, USB headset, external speakers to no avail.
Also, since last update, Dialpad is using almost 100% of cpu and loading slowly. The funny thing is that the first call is ok, then the speakers stop working and I can't hear the other person though the call goes through and they can hear me. The app is unusable now for business in my particular case.
