What is a gateway/proxy?An H.323 gateway/proxy is software or hardware that will route and/or proxy calls and translate them from one protocol to another. A gateway translating from H.323 on IP to ISDN is an example and the Open Source PBX Asterisk is another example of gateway.Doing calls using a gatewayDoing calls using a gateway is very simple. You can fill in the gateway hostname or IP address in the Gateway/Proxy section of the  preferences, and then simply use classical H.323 or CALLTO URL's to call users using your gateway or proxy.
You can not use CALLTO URLs looking on an ILS server when using a gateway or proxy. Notice also that it might be conflicting with your Gatekeeper following your Gatekeeper configuration.
