I have a PBX set up so that all the channels have "musiconhold=<classname>". We use all SIP phones and SIP to the VoIP provider. All channels have that setting. I directly call SetMusicOnHold(<classname>) for all incoming calls, but outgoing calls should be set by the "musiconhold=" configuration parameter. However, I still have circumstances that will play the default MOH class, but I cannot narrow down the circumstances which cause the <classname> setting to be lost. I'm using asterisk 1.0.7, Polycom phones, and a SIP provider. I have confirmed that all sip.conf entries have musiconhold=<classname> set. Most users are using the Polycom hold and transfer capability, if that should make a difference... Any other things I should look for to find the cause of the loss of that setting? Thank you. -- -M There are 10 kinds of people in this world: Those who can count in binary and those who cannot.
