[App_rpt-users] app_rpt issue with Polycom VVX phone

Hi everyone, I'm trying to help a friend troubleshoot an issue with his Polycom IP phones. He is trying to use a Polycom VVX500 to monitor his Allstar nodes, but the phone hangs itself up after 30 seconds. We've tried all sorts of things to cure the issue. It doesn't occur when using Cisco or Aastra phones, or any softphone we've tried. Just these Polycoms. Calls from phone to phone don't auto-disconnect either, this only happens when the phone is used to call *any* Allstar node. Any suggestions? Thanks. 73 Kyle K0KN
