The host starts the meeting with room name formadordigital.
Attendee tries to join the meeting and gets the 'Meeting room does not exist' error.
Rajesh has traced the cause to multiple rows in the portal database with the same ROOM_NAME but different USER_IDs.
Dimdim ID- formadordigital has ROOMNAME formadordigital and has the conference server pointing to promeeting. (which is correct)
Dimdim
ID-elisavetsky@fibertel.com.ar also has ROOMNAME formadordigital and has the conference server pointing to freemeeting. causing the error.
e.g khaud01.dimdim has khaud01
I think the approach for this is to
1) find all these anomlaies - Select USER_ID from USERS WHERE USER_ID<>ROOM_NAME;
2) Modify them all so that the ROOM_NAME Is the same as the USER_ID
