I am designing a VoIP network architecture using Xserves and OS X 10.4 Server entirely (where possible). So what im looking for is some way to authenticate my users. I have looked into it a little and think I need some kind of RADIUS\DIAMETER server? I’ve googled but its returned nothing. Because we are talking VoIP I will need some kind of accounting for billing reasons.
We also plan on covering a city with WiMAX once released and need a solution that can auth. both these clients and the SIP users. I plan to store the database of records on an Xserve RAID I dont know if that makes any difference.
If anyone can help me out that would be great.
