1. US 2. 07913904 3. I'm a new RC customer. Switched meetings from GTM and didnt have this problem on GTM. Some of my coworkers are reporting that some of their Meetings attendees are not able to join from their corporate PCs. They click the join link, browser opens and downloads RCMeetings, they are sometimes prompted to input name as usual, but at this point the process fails with no errors, it just quits on them, just nothing. On the host side however they see the attendee in their attendee list. The attendee can not hear or see anything. The app never fully opened for them. Dialing in does work. I think what's happening is these attendees are all customers of ours or prospects and they are all banks or financial institutions with strict network and/ or endpoint firewall rules, and RC is not whitelisted. We did not have this problem with GTM. Wondering if anybody else has seen this. I'm going to try to get more info from coworkers this week. RC Support this past week said they escalated this case to tier 2. They also said there has been some kind of similarly sounding issue with some RC customers of attendees not able to join meetings. I couldn't get a great idea if the issues were related, not sure. Any info out there would be great. Thanks. 5. Latest 6. Around 10
