iPhone XR calls timing out (hanging up) at intervals of 9 minutes
I initiate a Zoom conference call (audio only - not app) Tuesdays through Fridays from 5am-5:30am. Sometimes, there are no participants on the call. When there are no participants, the call will terminate nine minutes after starting. I then start the call again and again in nine minutes, the call terminates. This only happens when there is silence. No other calls I make terminate. This happens sporadically but often enough to be irritating. I opened a ticket with Zoom in April (when this started) and they have stated the problem was not on their end after researching it for two and a half months . I also have a ticket and community post open with Verizon and Apple. Thought I would check here to see if anyone else experienced this or if there is some setting that I am missing.
My thought is that the phone, carrier or Zoom have a timeout set somewhere if there is no one speaking.
Any ideas will be very appreciated.
