FreePBX (asterisk) Sipstation Cisco ASA 5520 Trunks Won't Register

FreePBX (asterisk) server ip 10.7.4.23

The is is what Sipstation is telling me they are seeing on their end:

2013-09-05 16:31:42.702739 [WARNING] SIP auth challenge (REGISTER) for [XXXXXX@trunk1.freepbx.com] from ip 10.7.4.23

So my ASA is showing the sipstation servers my internal IP address and not the external IP.

I can't setup a static nat for 5060 as I get an error: NAT unable to reserve ports.  I think this is because of the inspection map.

I have tried unchecking sip and H.323 in the service policy rules.

Wrong forum, post in "Security - firewalling". You can move your posting with the Actions panel on the right.

I think the show run of the ASA will be helpful (the internal Ip address of the PBX server is 10.7.4.23 right?)

Let me know,
