T38 picking random sip ports? Please Help

I've got some T38Gs with the newest firmware. We moved our PBX to another location, and these phones are now pointed to the new location of the PBX. They register fine, and make calls, however they go offline a lot and become unreachable because when I look at a list of the peers in my PBX I can see that the phone has selected some odd port like 8903, or 1343, instead of just 5060. These are the only phones and location to be doing this. So sometimes you look at the list of peers and everything is fine, they are on port 5062 and it's all good. Randomly, and whenever they feel like it they are switching ports. "canreinvite" is set to no.

I'm sort of out of ideas on how the phone seems to end picking random low number ports that I don't have set to let through the firewall.

Anyone seen this before? or have any ideas?
