Here is what I need is it possible to for example i dial out for autopatch its connected all the way up till some one gets on the phone then I would like to see it switch to Vox operations allowing the transmitter to drop so that it will reset the Transmitters Backup time out timer.. Example either I could Dtmf a set a numeral values into the repeater and drop the tx radio and bring it back up etc just need to go down for 5 seconds to reset every 2 minutes.. is this possible?? anyone out there have the same issues?
