hello Ryan,

thank you for your reply. without codec transparent, my phone rings but
when i answer i have no voice and it hangs up after 5 seconds. asterisk
says "no answer". this is so strange for me. i think media negotiation
failed, right? is there any hint to have h323 trunk to asterisk with
specific codec (not transparent one)???
