Dear All, Anybody worked on PJSIP with asterisk server. If so please look into the following issue and comment as well: My requirement is when I put the call in hold I need to play a WAV file to the remote end. But when I try to put the call in hold, the call seems to be in hold but the voice file is not playing back. I checked the asterisk log, it says "Started music on hold, class 'default'". In musiconhold.conf file, the default class is defined and the wave file is present under the "/var/lib/asterisk/moh" directory. But I don't have any clue why the wave file is not playing. Thanks & Regards, - Senthil
