Ok, this is weird.. sip.conf: [general] musicclass=natv_default [3254101] musicclass=classic [3254103] musicclass=natv_silence When 3254101 puts 3254103 on hold, moh played to 3254103 is natv_default. When 3254103 puts 3254101 on hold, moh played to 3254101 is classic. I'm not following the rules here... Doug.
