Hello,
We would like to use SER in a production environment and provide presence support to at least 5000 *online* users through a publicly available service.
We are particularly worried about scalability.
- How stable is the presence module?
What kind of presence do you want to use? - End-2-End: you do not need the pa module - server based: you do neet the pa module
the pa module is IMO not stable, and does support only certain clients.
Which clients do you want to use?
regards klaus
- Does it support RFC3857 to allow authorization management of
subscriptions?
- For such a big number of users, do we need several computers running
SER?
- If so, how can we ensure that all SER servers have the required
information to be able to send status changes to all users? Is that stored in a MySQL DB and if so, how is it determined which SER server sends the NOTIFY on state changes to all users having the user whose state changed in their list?
- Are there bandwidth estimations? I have the feeling that 5000 online
users will generate many NOTIFY messages due to presence changes.
- Is it possible to prevent MESSAGE requests to be sent following some
piece of information found in the database? We would like to connect SER to a SMS service, and prevent users to send SMS'es when their credit is not enough. That supposes some computation in the ser.cfg file, is that possible?
