Hi, We're using Polycom IP501 SIP phones (app version 1.6.4.0043) with Asterisk 1.2.9.1. I set up call parking last week and for a while, it worked great. It stopped working yesterday, all of the sudden. What happens is that when the phone user dials #999 (our parkext), the call does not get parked and the caller hears the DTMF. Actually, they don't hear the DTMF, they hear a popping noise as the keys are pressed. The configuration files have not been changed since call parking was initially enabled. I'm running a console with -vvv and I don't see any errors reported. Any ideas? Thanks... Chris
