hi, i have been looking for a way to authenticate users based on the IP from they come from . Also i would like to limit the number of channels ( simultaneous calls) that each user can make . is their any way to do this using kamailio 3.0 and siremis 1.0 ?
my configuration is like this:
sipphones --->UserGroup1(Asterisk PBX)---->KamailioSipProxy--->AsteriskPSTNGateway--->PSTN
1. there can be many softphones on the user group 1 and there can be multiple calls coming from there at any time. 2. UserGroup1 is actually another SIP proxy [asterisk] with a fixed public IP 3. Kamailio Sip proxy is the one i am trying to configure . I would like to authenticate UserGroup1 based on its public IP address 4. From kamailio , calls will be forwarded to a asterisk pstn gateway. I would like to put restriction on this one : " User group 1 can not make more than 5 concurrent calls at a time"
can anyone give me some suggestion or point me in some direction where I can do some reading on this one.
Aslo , what would be best way to bill this UserGroup1 ? Using FreeRadius and CDRTool ?
