I am setting up a conference call in Freeswitch having 20 participants. 

I am facing a problem where sometimes voice from a single party who is the moderator is not audible to rest of the participants even though the GSM signal strength is good.

In one scenario, the conference lasted for 45 minutes, but the voice from the moderator went away after 40 minutes. Is there any timeout for conference
