[Freeswitch-users] Configurable Hold Music while conference in freeswitch

Hi, I want play configurable hold sound while conference using freeswitch. I am using "moh-sound" variable in conference.conf.xml as follows. <param name="moh-sound" value="/srv/sounds/${uuid}/knowlus_hold_music.mp3"/> The uuid is the variable "variable_uuid" in the events comes from freeswitch,but the freeswitch is unable to expand this variable and error comes as follows : [ERR] mod_shout.c:683 Error opening /srv/sounds/${uuid}/knowlus_hold_music.mp3 [ERR] mod_shout.c:862 Error from mpg123: File access error. (code 22) Freeswitch is not able to expand the variable as variable exists and the file which i want to play also exists. Can anybody help me out in this ? With Regards Harsimran Singh +91-9711271158
