   We're getting reports of delayed audio from some customers using SIP dialin and dialout. When the phone user joins the call, they can talk and others will hear them, but the phone user won't hear any audio from other call participants (bot or human) for the first 20-30 seconds. We're continuing to troubleshoot the issue, and we'll post here as soon as we have more info.
