Re: twenty thousands (20, 000) users, which asterisk and how many servers

Thanks for all for the help and kindly reply.

One last point that will help me alot:

I am thinking to have 4 Servers running Asterisk and 2 Servers to be for database. The load to be distributed on the 4 Asterisk Servers with ability to be redundant (using any redundancy technique). The 4 Asterisk Servers to take the configuration from the Database Server and actually because there is 2 Database servers, then it will be redundant to each other (in case one database failed, the other will take over).

My question is:

Is it really possible to have the asterisk configuration in the database server instead of having it in conf files? HOW? I am asking this because what I noticed in AsteriskNow and in A2Billing and Vicidial or Goautodial that whatever I do configuration in the GUI, then the configuration will be generated in the conf files, so Asterisk will read from the conf files and not from the database directly. Is it right or I am confused and there is something else?

If there is a method to let the configuration to be taken from the database (and not from the configuration), then HOW? Because even in AsteriskNow, the configuration will be generated in a conf files. 

Special thanks for the advise.
