If you are using IAX2, you don't need to port forward the ports.
Just have PBX2 register _often_ and that will keep a mapping in your  
router.
(also you _don't_ need to enable _any_ TCP ports - IAX2 is UDP only)

If the problem does not go away when you turn off port forwarding, do  
an iax2 debug on PBX1 and
send me a log of a call that fails and I'll take a look.
