Hi guys,

I'm designing a new service for a client and I was wondering what your opinion is of the 2 options I'm considering to separate users on the server. Basically I want to create closed groups where each user can only call and receive calls from members of the same group (single domain install). Initially I was thinking of just forwarding all the invites to FS and using the dialplan to enforce this segregation, but now I realize there is a groups module in kamailio too.

Which 2 courses of action do people recommend? I'm more familiar with FS than Kamailio, so it would be easier for me to just forward everything to FS, although that will be more expensive and probably unnecessary if I could do it all in Kamailio with Siremis.

Would kamailio's group module do the trick? Are there any tutorials out there I can follow?

Group module should do it -- you can use get_user_group() for the caller and then check if callee is in the same group via is_user_in().

But it is not the only alternative in Kamailio -- I would add a new column to subscriber table and load that via load_credentials from auth_db module (which is done at authentication time), then check for callee via sqlops.

If i need caching, either htable or mtree are good options, a matter of user id (if it is digit only or any alphanumeric set of chars).

Cheers, Daniel
