The term IRLP - Internet radio linking project. it is made so that you can connect to a repeater or disconnect from it but used primarily to have repeaters Linked all the time. the win system is designed that you must be connected all the time to each other. in allstar you can setup an IRLP node or just link to the allstar Hub into the WIN system. IRLP is proprietary software where Allstar or asterisk is open source and you can make changes to it without permission. Echolink connections are not allowed on IRLP. also IRLP you can not have anything transmitted but just the Audio voice of the operators. NO DTMF no ID’s and no Tone Beeps are allowed to go thru.
