I am looking for a complete SER configuration. Which can do the following. - Can do load balancing for our asterisk server farm (4-6 servers). - Can do accounting. - Least cost routing. - Can do IP based authentication. Mysql trusted table will have the list of IPs in trusted table and see allows calls from those IPs. - Should have some kind of web interface for client to see their account and call logs from one account for all IPs. - Web interface for cutomer support people. Where they should be able to manage the accounts. Make changes, check the amount used. - Each account can have multiple IPs who will send call and ser will forward those calls to my service provider. - Should disconnect calls once the account is out of credit. I have seen multiple tools and modules that can do all or some of these. Like SER, Serweb, FreeRadius, CDRtool etc. I am able to make them work one by one. but making a package of all this and then doing testing and all that is taking too much of time. So now I am looking for some commercial solution that can handle all this. Can some one point me to good source that can do all this. I will be even interested in paying someone who has done all this and can finish that for me in few days. Thank you, -Jai
