This board "Jobs - Requests for Consultation" is meant for offering to pay someone to work for you. If you merely have a question about how to do something in Vicidial, please remember to post in the "Support" board instead.
I will now move your post to the support board.
And to answer your question: The administration web interface stores data in the database server. There is only ONE database server, so regardless of which server you use as an administrator to make changes, those changes will be stored in the same place. Which means: It doesn't matter which web interface you use for administration at all. Use any of them. All of them. All at the same time even. If you have several administrators all making changes on several campaigns, users, DIDs, etc., they do not have any requirement to be on a specific web server when making their changes. The only exception to this rule: If two users make changes to the same record, the last one to hit "submit" wins
