Select your SQL Server Edition

Rule of thumb

We recommend to review this topic and select your SQL Server edition based on your requirements, but here is a rule of thumb to simplify your decision.

Phone calls stored in the system at any momentRecommended SQL Server edition
less than 1.000.000 calls and instant messagesExpress Edition
If the Full-Text Search feature is needed, then choose SQL Server Express with Advanced Services.
between 1.000.000 and 10.000.000 calls and instant messagesStandard Edition
more than 10.000.000 calls and instant messagesEnterprise Edition

If you have configured Data management policies in your system that automatically remove calls, you can plan for the maximum amount of calls that you store in the system at any moment, and not the total amount of calls you are record.
