Chatting in ProCall Client (using Microsoft SQL Server) is not possible: the chat window remains empty.
UCServer reports the error "EDatabaseConnection::GetEvents;Field 'ReplyToSeqID' not found".
As of UCServer version 184.108.40.2062, SQL table "ChatEvents" has been extended by columns "ReplyToSeqID" and "ForwardedFrom".
In certain constellations, the SQL database is not updated during an update/upgrade of the UCServer.
For example, when updating/upgrading from 220.127.116.1166 to 18.104.22.16848, the columns "ReplyToSeqID" and "ForwardedFrom" in dbo.ChatEvents may not be created.
Check if the columns "ReplyToSeqID" and "ForwardedFrom" are present in the table dbo.ChatEvents.
In UCServer version 7.1.2 and higher, this behavior no longer occurs.
As a workaround, you can manually create the columns ReplyToSeqID (int,NULL) and "ForwardedFrom (nvarchar(MAX),NULL) in the SQL Server table dbo.ChatEvents.
