At the ASDF BOF this morning, Michael John Koster, who I will CC once I have
a ticket number, got his audio cut off after about ~20s.  He reconnected
(shift-reload, I think), and then again was cut off after 20s.

I expect that this is a local firewall issue with the pinhole for his
outgoing RTP.  Probably unsolveable unless one can force the connection to be TCP.

Yesterday, at TEEP, this also happened to Mingliang Pei, who I will also CC.

Hi, Michael Koster <> dropped off of ASDF this
morning, and dropped off of TEEP on Monday

I suspect local firewall issues with outgoing RTP.
Maybe there are some similarities that will make investigation helpful.

I Michael, I suspect some firewall kicking in as well. I'm happy to have a dedicated test session with Michael Koster and/or Mingliang Pei to try to sort this out. A working TCP fallback is already provided via TURN, BTW.

They can contact us directly at ietf@… and we can schedule a test session wither prior or after the meeting sessions.

I'm closing this ticket.
