An unhandled exception was encountered in Conferencing Announcement Service.
In a Skype for Business Server 2019 environment, I see this error on the Front-End servers Log Name: Lync Server Source: LS Conferencing Announcement Service Date: 31-03-2020 14:07:43 Event ID...
Just for information I got this answer from support
This an acknowledge issue for skype 2019 that occurs when you create a conference through UCMA on a skype 2019 environment and during the following conditions:
• The issue is noticed if we have a NIC card on the FE server, which provides incorrect speed information.
• Bandwidth reported on SDP exceeds 2TBPS
• Previously we engaged our Product Group for assistance after in-depth analysis by the PG, they concluded the issue with the NIC card.
• Time-out interval must be less than 2^32-2 - Indicates that cx has a NIC card for 4TBPS
• Please replace NIC card with 2 TBPS speed on the server and check the behavior

Thanks, We have the same problem here. SFB 2019 / Win 2019 with callcenter Trio 8.x,
The Front End servers is running on VMware with 10 Gbps NIC...The answer from Microsoft is to use "NIC with lower than 2 TBPS". Is it Terabit / second ?? I don't understand.
- The customer didn't want to do anything about this error anymore, but yes it is Terabit per second
