I currently have a Hub Node setup. A radio node will follow. My goal for the moment is for a remote node to connect to my hub and then for my hub to initiate an IAX call over to my asterisk PBX where it will ring a particular extension. This mostly works, but the remote node remains keyed up throughout the connection. I am seeking a solution. Based upon a suggestion from Mike the Midnight Engineer, I took a look at the events programming description. I was able to figure out after a few reads how to use the RPT_NUMLINKS variable to trigger an autopatch dial macro when the value goes from false to true. So a remote connection comes into my hub and the designated extension on my PBX rings. Audio is passed both directions. However, as stated above, no PTT control. I have looked at the duplex and vox timeout configuration variables and have tried a number of approaches without success. Any thoughts or direction would be most appreciated. Thanks, Dan K2DLS
