> When a packet is received twice (and though ast_data_buffer_put would report "Packet with position ... is already in buffer. Not inserting.") the payload will never be freed resulting in a memory leak.
> This behavior could be observerd with asterisk 16.9 during WebRTC conferences when some clients had bad connections and some packets needed to be repeated.
> Attached you'll find a patch that fixes the issue.
