[Freeswitch-users] Conference with flags wait-mod|nomoh plays MOH

Hello, I have configured a audio conference with flags wait-mod and nomoh. I make a call to the conference as the first member and I listen moh, instead of silence. I am using FreeSwitch 1.6.17 If I configured the audio conference without the flag wait-mod, when i enter the conference I have silence and it is ok. This is a bug or this is the right behavior ? There is any option that i can configure so when i configure the conference with flags wait-mod and nomoh, when the first members enters, it get silence? Thanks in advance. Best regards, Jose Lopes
