Hi Thanx for the useful information you provided earlier. Now at least I have decided to use the parent-child approach. For load balancing Alternate GKs approach can be utilized at both:parent and child level,right? Now I have few further queries Is it possible for child GKs to select the Terminating end-points(GWs) from database, using Radius? Actually I want to select the terminating gateways from radius on ARQ in Parent child approach. So far I can see that ARQ never gets to child. Parent recieves the ARQ & responds with an ACF. Child just receives: ProxyL Connected from parentIP:4583 Q931s Received: Setup CRV=1472 from parentIP:4583 (CALL) Call No. 1, total sessions : 1 Successfully logged event 1 for call no. 1 Send to ParentIP:1719 and then child sends an ARQ to parent!!! Parent then responds with ACF and Child initiates the call signaling with Terminating endpoint specified in ini. CHILD NEVER GETS A CHANCE TO LOOKUP THE TERMINATING ENDPOINT FROM DB. Secondly I want to know How can I register originating gateways at Parent level for incoming calls? Either adding them as [RasSrv::PermanentEndpoints] in parent's ini with their prefixes in [RasSrv::GWPrefixes], I tried it but call never gets to parent from an originating GK(which can be a gateway as well).i.e. Endpoints -> OriginatingGKs -> Parent GKs -> Child GKs -> Terminating GWs The Parent GK is supposed to receive calls from Originating GWs/GKs and will pass them on to parent which will forward it to respective child, and child will select the terminating gateways from DataBase. I hope I dont sound too complex and it makes sense.
