Re: [OpenSER-Users] Limiting maximum number of concurrent calls

Hi,

We are running openeser version 1.2.2. Currently we have defined 3 groups of subscribers. We have a requirement of limiting max number of concurrent calls per group. For example, 10 maximum number of concurrent ( incoming /outgoing ) calls for subscribers belonging to group 1. How do we go about it. Any sample config will be appreciated.

As far as I know, there is no inherent mechanism for doing this in OpenSER.

You are going to have to keep state for each SIP transaction going to a particular subscriber group - perhaps using a database. Using request and reply routes, be able to store calls in progress. Then, count them to enforce the cap.
