ALG Blocking RTP and SRTP in SSG550

Hi guys I am having a problem with Audio.
I have asterisk server for which I have a MIP on the outside interface untrust which is in DMZ. Its sending an inbound call received from interface trust going to a server on the untrust. Traffic gets to the Asterisk server and audio works fine between Trust and DMZ but when I make a call coming from Trust going to DMZ and then forwarded via trunk sip to unstrust with ALG enabled I have no sound as soon as I disable ALG it works fine. I spent hours trying different things but can not get it to work.
I really like the concept of ALG and would love to keep in enabled to avoid opening 13K ports in UDP. But for the life of me I can’t get it to allow sound to pass thru.
Can anyone help please
