Greetings, Complete newbie question so apologies here. I am trying to connect our test Asterisk server with a number of SIP clients to a H323 PSTN gateway, the basic connection of SIP Asterisks works a treat however the h323 is causing problems. Box is a Cisco IP-IP gateway running in non-gatekeeper mode but I cannot work out what to configure to make this work. Sip >Asterisk >Cisco IP-IP is the call flow. I have this working with our call manager internally replacing the Asterisk server however we are trying to evaluate the IP-IP gateway so any assistance in this would be gratefully appreciated.
