CallManager 40ms synchronization

Does anyone know what occurs when you exceed the 40ms syncrhonization between pub and sub?

Re: CallManager 40ms synchronization

Complete and utter madness :o) The worry regarding the round trip latency has to deal with the replication of the SQL database from the pub to the subscribers.

Everytime you change anything in the database, (ie change call forward status) a record is updated on the publisher and is then pushed to the subscribers.

All kinds of fun things happen when the databases fall out of sync. Phones registered to one CallManager think a line is still forwared when phones registered to another CCM don't etc etc.

There are very few design scenarios where a centralized call processing model doesn't work...so I definitely lean that way 99.999% of the time.

Hope this helps.
